中文用户讨论@vbulletin-china.cn (http://forum.vbulletin-china.cn/showthread.php?p=5635)

(note: do not apply this patch on vBulletin 3.7 as it's included already)
This patch allow you to use XCache (http://xcache.lighttpd.net) as a datastore cache in vBulletin. This is definitely your choice if you have installed and enabled XCache on you server already.

Take care that this is a beta version and was not heavily tested. And i'm not familiar with vBulletin source code as i just started reading it today, but i don't have any difficulty reading it thanks to my years of php skill :)

Take aware that some vB plugin is not compatible with vB_datastore_*, not just vB_datastore_XCache. So, in case you find vB_datastore_XCache won't work, you'd better try datastore to file or memcache. If one of the others works but not vB_datastore_XCache, do report it to me so i can fix it.

Pre-requirement

a working php installtion (http://www.php.net)
a working vBulletin 3.6.5 installtion (http://www.vbulletin.com)
a working XCache installtion (http://trac.lighttpd.net/xcache/wiki/InstallFromBinary)
set "xcache.var_size = 10M" or so in php ini

Install the modification
for those of you who can't run "patch", u may patch the file manually

download 61372 (class_datastore_xcache.php)
save the file as vBulletin.3.6/upload/includes/class_datastore_xcache.php
open vBulletin.3.6/upload/includes/class_datastore.php in your favor editor
add a line in class_datastore.php (see below)
update upload/includes/config.php to enable it (see below)

example class_datastore.php after modification:

}
return true;
}
}

// add class_datastore_xcache, enable it in config.php
require_once(DIR . '/includes/class_datastore_xcache.php');

example config.php after modification:

// vB_Datastore_Filecache - for using a cache file
// $config['Datastore']['class'] = 'vB_Datastore_Filecache';
$config['Datastore']['class'] = 'vB_Datastore_XCache';
// vB_Datastore_Memcached - for using a Memcache server
// It is also necessary to specify the hostname or IP address and the port the server is listening on

Trouble Shooting
q. i have multiple vBulletin instance installed, the seems to mix data after install this plugin
a. this applies to apc too because, if you wanna fix it, try
open class_core.php, look for:
$this->prefix =& $this->registry->config['Datastore']['prefix'];
and modify to:
$this->prefix = $this->registry->config['Datastore']['prefix'] . $_SERVER['SERVER_NAME']; // or HTTP_HOST

q. Warning: unserialize() expects parameter 1 to be string, array given in $a.php on line $b
a. upgrade your plugin/hack that $a.php belongs to, e.g. vbjournal/vbgallery etc. OR open $a.php and locate at line $b, remove unserialize call, e.g.:
replace $var = unserialize($this->data);
with $var = $this->data;
be careful do not remove the whole line, just the unseralize( and )

Man..what u have done ?
Simply tremendous..........

Xcache rocks............

sure it will work better than others..
Xcache is working simply good......in my vb board...even it works better than eAcc.
it reduced my server load more....

can u say how much ram will be needed for using this? min.requirments?

Thanx......

Zia

03-03-2007, 06:28 AM

Hope to get it with in vb at next release...

i gez after install it we wont need memcache any more ????

03-03-2007, 06:47 AM

Sorry, all this talk is way over my head, can someone explain what this is about in laymans terms please?

Do i need to install this?

Zia

03-03-2007, 07:04 AM

helo bashy..

like; some of us using eAcc or APC or Xcache for php accleration.
If u have Xcache installed on ur box for php cache/optimize u can install it for datastore cache.

atm we are on Xcache and it really works nice than eAcc.And it reduce more serverload than eAcc.

Xcache is perfectly working with php5.2.* series.
http://trac.lighttpd.net/xcache/
Xcache have option to cache php & variable.....to enable datastore cache for vb+xcache.
Gonna install this patch for data-store cache.

03-03-2007, 07:12 AM

Ah right ok thanks Zia i understand now :)

More info on this woul be good. I just tried to install this and got errors. I didn;t change the var size from 0, plus I assumed the location of the attached php file.

Please can more details be added to this hack as I would like to use it.

Thanks.

i have updated the topic again.
setting "xcache.var_size not 0" is same as "xcache.size"
xcache.var_size = 10M or so is fine, just resize it for to fit your needs.

you gotta copy the content of the whole php file i attached into class_datastore.php, there's no new file is created or added

I gez u can ..i gez
to use this(this thread) mods..u must have Xcache install in ur box
Download Win32AutoBuilds at here/XCache-VERSION-php-x.y.x-Win32-rREV.zip. This is an official SvnSnapShots autobuild, but NOT release version.
Check InstallingAsPhpExtension for instructions. (the doc is not updated for win32 yet)
It can be very hard to compile for Win32. If you're gonna do it yourself, Cygwin is required, and check the simple README to accomplish the complex job.

Disassembler is avaiable in source but missing one file due to license problem, so not built into win32 binary package. btw, disassembler isn't designed to work with commercal encoders/encrypters.

(The Author phpxcache can explain u better)
After u got xcache installed on ur Box..U can use this mods for datastore cache.

Thanks.

Thanks for ur interest. I will try to provide u some info..see it it helps u a bit..

See bellow xcache.ini of our box

; select low level shm/allocator scheme implemenation
xcache.shm_scheme = "mmap"
xcache.size = 64M
xcache.count = 4
xcache.slots = 8K
xcache.ttl = 0
xcache.gc_interval = 0

; same as aboves but for variable cache
xcache.var_size = 64M
xcache.var_count = 4
xcache.var_slots = 8K
; default ttl
xcache.var_ttl = 0
xcache.var_maxttl = 0
;xcache.var garbage collect interval set to 6 hour.
xcache.var_gc_interval = 21600

Pls follow the red color text
xcache.size & xcache.var_size both set to 64Mb .
And ur using 100 Mb for xcache.size . :confused: did u really need that much memory ?:eek: we set 64MB.33Mb used and still 31MB is free out of 64Mb. when vbplaza on it just consume 3~4Mb more + few more php cached.

check ur xcache admin cp & if needed reduce allocated memory OR if u got enugh memory at ur box/server ..then u can use 100MB+100 Mb.

Point is that u have to put same MB of memory at xcache.size & xcache.var_size

php file in the attachmnet
you gotta copy the content of the whole php file i attached into class_datastore.php, there's no new file is created or added

MikeWarner

03-03-2007, 03:38 PM

No - I need 100mb. I have tried to reduce it, but was getting ooms using 90mb. I'll give it a try later. Thanks.

03-03-2007, 03:54 PM

ag OOMS ..thet u obiviously need 100 MB..(wondering how many things ur using)
then did u try 10 or 20 Mb for xcache.var_size ?

03-03-2007, 06:50 PM

Thx guys for the reply... i got it working now.. is there anyway that i can see stats of the site how is it going... what is cached etc?

bluechris

03-03-2007, 07:33 PM

Nevermind i got the admin page working and i see the statistics... the point is i dont see cache working really... or i am mistaken.... see my php.ini settings

[xcache]
xcache.shm_scheme = "mmap"
xcache.size = 32M
xcache.count = 2
xcache.slots = 8K
xcache.ttl = 0
xcache.gc_interval = 0

xcache.var_size = 32M
xcache.var_count = 2
xcache.var_slots = 8K
xcache.var_ttl = 0
xcache.var_maxttl = 0
xcache.var_gc_interval = 300

xcache.test = Off

xcache.readonly_protection = Off
xcache.mmap_path = "c:/temp"

xcache.coredump_directory = ""

xcache.cacher = On
xcache.stat = On
xcache.optimizer = On

[xcache.coverager]
xcache.coverager = Off
xcache.coveragedump_directory = ""

Also in admin page of xcache i see this results in the attached gif.

the only 4 hits that had cached is the pages from admin of xcache, do i need to do something extra in my VB? or anywhere else?

i assume you're usig windows, can u tell me how is your php installed? not the installtion steps, but about how it looks like. iis? apache? mod_fastcgi or not?

See Faq: Why is my cache being cleared? (http://trac.lighttpd.net/xcache/wiki/Faq#Iseejumpyhitsinadminpage)

bluechris

03-04-2007, 04:35 AM

I use IIS with php 5.2.1 ... but i got the big picture from the links and other search i did on web...
I think the problem is that i use fast-cgi..... this dont not work good in windows cause caching programs cannot share among many worker processes that windows run for each user ... my 2 options now is run as isapi i suppose or w8 for something else...... i dont know what else i can do.

Ur on win server?
seemed that ur cache is working...

i m confused ur var.cache is working or not :confused: .....did u follow all the steps properly to enable var.cache?

Yeap i got same statistics for var cache... says that hasn't cached anything.

you gotta remove the old patch that you applied (inserted) to use the new installtion way.

the php cache part and the size of var cache looks good. but var cache is not caching anything in your case. did u request the vBulletin first to let it cache something in?

Zia

03-04-2007, 09:16 AM

Just spotted something. I'm using 3.6.4. Is that ok?

Thanks.

as per screenshot...u set xcache.count = 4 (ur processor count) & xcache.var_count = 1?

seemd ur var.cache isnt working.....
ask phpxcache .. diff. of xcache.count & xcache.var count will be a probs or not...

vb3.6.4 or 3.6.5 wont be a problem

I stay with xcache for template caching

dont get ur word..that means after install this data store cache modification u faced mentioned error?
i would like to request u to provide as much as info possible for u to provide phpxcache for proper diagonisis & soltion...
or if u face error with Xcache drop ur issue http://trac.lighttpd.net/xcache/newticket .Soon..very soon u will get the reply..

I'm currently using APC on my major vB forum do u suggest me to switch to XCache ?

like wise i was on eAcc and then i moved to Xcache & suggest every one to switch to Xcache.
Do u know why? Coz,this is really too kool it works gr8 with less memory consumption even it makes my forum more faster than before.
and the main reason is that the author is very much agger to digg any bug & solve it ASAP.
wich i didnt get in eAcc or APC.

Compatibility problem.

Great hack unfortunately it's not compatible with Photopost vBGallery.

I'm receiving all kind of weird errors:

Phpxcache do you have any idea what could be the problem ?

Correction...it's not compatible with any of the large plugins like vBlogetin or GARS.
Errors like above everywhere :(

03-04-2007, 11:29 PM

does vb_Datastore_File works? (i can't recall the name, u may check the class name in class_datastore.php)

if yes, it's vB_Datastore_XCache problem, otherwise, it's the problem between vbgooglemap and vB_Datastore.

i'd like to know what's going on. hope i know how to install the plugin. i'll check it later, and/or you trace it down.

Thanks Zia,

It has nothing to do with xcache.
I'm running xcache since the 0.x releases (before anyone used as phpcache at vbulletin). Everything runs just fine.

This plugin only works well with stock vbulletin.

It doesn't work well with the plugins. (Not only vBGallery, Geek Article System, and vBlogetin...it doesn't work with vBShout...)

yup, i thought i can be vB_datastore_XCache plugin problem, but i copy the code from vB_datastore_APC, so it can also be problem of other plugin that isn't compatible with vB_datastore_*

thanks for your confirmation.

I have not installed this but I have fixed PhotoPost vBgallery to work with Memcache.
- I think it will support other external cache programs also.

The problem was the way the original scripts are designed.

I do not have a full list but I am changing old calls to datastore items for vBgalery 2.2.

EX:

New:
$categorycache =& $vbulletin->gallery_c_cache;
$galleryoptions =& $vbulletin->adv_gallery_opt;
$gallery_permissions =& $vbulletin->gallery_ugroups;

vs. old way
$categorycache = unserialize($vbulletin->gallery_c_cache);
$galleryoptions = unserialize($vbulletin->adv_gallery_opt);
$gallery_permissions = unserialize($vbulletin->gallery_ugroups);

I have a windows system w/ memcache enabled and the gallery working with the new changes. With the current code in the gallery APC, Memcached setting stop the gallery from working.

I will also change the code to build datastore.

New:

Old:
build_datastore('name',serialize($field));

Changes as these may also fix other scripts out there.

Hey Zachariah,

Thanks for this, but where do I made these changes?

I have not installed this but I have fixed PhotoPost vBgallery to work with Memcache.
- I think it will support other external cache programs also.

The problem was the way the original scripts are designed.

I do not have a full list but I am changing old calls to datastore items for vBgalery 2.2.

EX:

New:
$categorycache =& $vbulletin->gallery_c_cache;
$galleryoptions =& $vbulletin->adv_gallery_opt;
$gallery_permissions =& $vbulletin->gallery_ugroups;vs. old way
$categorycache = unserialize($vbulletin->gallery_c_cache);
$galleryoptions = unserialize($vbulletin->adv_gallery_opt);
$gallery_permissions = unserialize($vbulletin->gallery_ugroups);I have a windows system w/ memcache enabled and the gallery working with the new changes. With the current code in the gallery APC, Memcached setting stop the gallery from working.

I will also change the code to build datastore.

New:
build_datastore('name',serialize($field),1);Old:
build_datastore('name',serialize($field));
Changes as these may also fix other scripts out there.

vBlogetin doesn't use vBulletin's datastore functionality, which means this hack will not affect it.

Code Monkey

03-31-2007, 05:04 AM

This is great, thanks for your work on this. It's working great for me. Except it kills vBadvanced. So I put the following in config.php until I figure out why.

if(!defined('VBA_SCRIPT'))
{
$config['Datastore']['class'] = 'vB_Datastore_XCache';
}

I also found that if you are running more than one instance of vBulletin on the same server then you need to put the following above the declaration of the datastore class in config.php (above)

$config['Datastore']['prefix'] = 'prefixchoice';

Of course you need to choose a unique prefix for each site. The table prefix will do.

I had to turn this off. It doesn' seem to update the cache from the command line. Meaning, when a script that updates the datastore is run in a browser it works fine, when it's run as a server cron it does nothing. I'm not sure if it's a vBulletin issue or an xcache issue. I just have no time to look into it right now.
Hi,

LOL, very cute showing me my own hack. However, I am refering to server cron. I have some very intensive scripts on certain sites that run every few minutes and need to be run using the command line.

Now that the xcache forums are back up I see it does not support cli yet. So I will wait. Meanwhile, it does a great job caching and optimizing the PHP scripts.
I knew i'd seen your name before :P

I also have cronjobs set to run every few minutes (via cpanel - rsync between multiple servers)

They are fine for me.

Personally, I would not go this way.
I prefer installing memcached (for datastore) then use XCache for the rest of the php files.
From my tests, this combination improves the VB performance by over 250%. Expecially if you use 2 servers or more for your site.

An example: With the above setup, the forumhome memory usage drops from 3,500KB to 720KB.
The rest is cached by the memcached/XCache combo.

Still, that does not say your code is bad. Congrats on a good idea. :)

u need no hack but just install XCache extension to cache php.

this hack/addon just allow you cache datastore to XCache beside memcached/file/apc/...
so if you wanna use memcache for DB/datastore, just install XCache extension but not this hack.

the meaning of "datastore" is defined by vbulletin, not me. it's simply a DB cache, nothing more, nothing less.

phpxcache

07-01-2007, 12:39 PM

XCache datastore is same as file/apc/memcached data sore, u just pick one of them.
1. use XCache for php caching, and/or:
2. use of and ONLY one of "ea/file/apc/memcached/XCache" for datastore caching,
u can't do Xcache_datastore + memcached_datastore or anther combination, but you can
xcache_php_caching + xcache_datastore
or xcache_php_caching + memcached_datastore
or xcache_php_caching + file_datastore etc

"ea/file/apc/memcached" is officially supported by vBulletin, this hack only add and XCache optional choice for you.

how do you load xcache.so?
extension=xcache.so
OR
zend_extension=/path/to/xcache.so

try the other way

Helo phpxcache..
can u say is there any way to use this varcache with particular Vb Module like Vbradio & Tv (https://vborg.vbsupport.ru/showthread.php?t=152037&page=44)?

Tried this out... Seemed to work great except some strange problems with vbjournal and photopost gallery (2.3 -- still problems with xcache datastore).

I had to disable it due to the plugin problems. If there was a guide on how to change plugins so they are compatible that might be helpful.

Hmm, I got xCache 1.2.1 working, but for some reason the Clogs keep on going up and up, much faster than anything else, plus it is always compiling... Searching on line other people have had the same problem, but doesn't look like there is a solution. My setup win2003 - Apache v2.2.3 - php5.2.4

Is there any way to disable this for certain mods or modify them to work with the xcache datastore?

If the datastore won't work, is there still some benefit to the filestore? I noticed that works with all my mods and Xcache actually caches it as a php file.

Are you talking 15 seconds as reported by vbMicroStats or some other method? I have 3 large VB forums (almost 3mil posts together) on 1 dual xeon and have load times of less than a second on the forum home. Plus the server runs about 10 other busy sites, an online learning center, some old UBB forums, etc.. Of course I do have 4GB and scsi raid 5. Still, your server/vb must not be optimized.

xcache.ini ??

If it is installed correctly, those fields should be found in your php.ini file. /etc/php.ini

Hence, what the error message is telling you to look into.

Not sure what else is going on with your setup unless you can give some more information. I've got xcache and this mod running on two dedicated servers now.

well, some how for my setup php4.4.7 when i include

Does this mod work when you have more than one VB installation on a server? I've got two installs but the variables are clashing with each other if i enable the mod on both vb installs at the same time.. :(

this applies to apc too, if you wanna fix it, try
open class_core.php, look for:
$this->prefix =& $this->registry->config['Datastore']['prefix'];
and modify to:
$this->prefix = $this->registry->config['Datastore']['prefix'] . $_SERVER['SERVER_NAME']; // or HTTP_HOST

I've searched this mod for vbseo as in 3.1 it now supports xcache, but the only references I found were that vbseo works, but no information about the new version. Anyone know if there's any conflict between this mod and vbseo's xcache support?

Thanks,
Ron

I'm running vbseo 3.1, with xcache and this mod.

I was running this mod and had xCache support turned on for vBSEO 3.1.0 but ran into the problem of the preceding post. Disabling this hack solved the problem while I've been able to leave Xcache on for vBSEO. I may try APC though based on that thread that I just referenced.

SemperFideles

Sandman,

Misses, hits, and clogs are OK. What you need to watch out for are OOM's. I've found my server will actually crash if I don't watch that. If that happens then bump up your xcache.size and/or xcache.var.size until you hit the sweet spot.

Right. Though you can also just increase the xcache.size and the xcache.var.size to fix the problem if you haven't maxed it out.

The default is set to xcache.size=32M and xcach.var.size=0M.

My board requires that my xcache.size=140M and my xcache.var.size=2M. I also have my count set to 2 for the number of processors.

As you can see, even though my xcache.size is 140MB and the xcache.var.size is 2MB (even though the variables get most of the hits), this is still way less than the 4GB of system RAM on my server. You do not necessarily need to upgrade your server to fix your OOM problem but simply change a couple of variables in your php.ini.

Disable other extension and see

;zend_extension=/usr/local/Zend/lib/ZendExtensionManager.so
;zend_extension_ts=/usr/local/Zend/lib/ZendExtensionManager_TS.so

Save and restart httpd, check php.info and see xcache is installed.

Can someone post a working php.ini (the xcache part) ?

I continuously get the following error:

check your phpinfo() page and see if XCache gets loaded and set properly, make sure you've updated the correct php.ini

Are there ways to make MORE use of the datastore with vBulletin? Only 24 things are caching in Xcache and they're barely taking any space... I'd just like to make more use of my var cache. :)

Hello

An information please...I use vBSeo 3.1

In Control Panel vBSeo there is : Caching Options

Cache Type (BETA)
Select the caching system to use from the list below. Make sure that your server supports the selected cache type.

memcached
APC Cache
XCache
eAccelerator
If I active XCache here (for vBSeo options), Can I also install and active Datastore Cache to config.php or not?
Two activations can create some conflicts?

Thanks :)

Just in case no one has noticed yet - xcache support has been added to vbulletin 3.7.

I saw where he said not to install the patch in the OP. I assumed the file was included somewhere in 3.7 but I haven't been able to find it.

Yes, I'm a newbie. :o

Just remove this modification then in ./includes/config.php
Search for:
// $config['Datastore']['class'] = 'vB_Datastore_Filecache';
Add underneath or replace it with
$config['Datastore']['class'] = 'vB_Datastore_XCache';

I applied the patch, and all I get is a blank page when accessing the forum.

are you php 5.0.x?

It's unsupported by xcache apparently. I get the blank pages too.

Amenadiel

02-29-2008, 10:31 AM

This is weird. I have applied the patch, but xcache isn't showing datastore items as cached. Just regular php: no language, usergroup or anything.

I have already uploades class_datastore_xcache.php, edited config.php and class_datastore.php. Should I enable something else somewhere? What am I missing here?

Icy

02-29-2008, 05:05 PM

In your php.ini. i.e.
; same as aboves but for variable cache
xcache.var_size = 6M
xcache.var_count = 4
xcache.var_slots = 8K
; default ttl
xcache.var_ttl = 0
xcache.var_maxttl = 0
xcache.var_gc_interval = 0

Hi moo
such a nice work! my huge forum is on the fly with lighty n xcache

Opcode cache works like a charm, Variable cache is workin too but there is sth wrong with this class to me
it kills my forum when i swich datastore to this class! server load increases upto 12 then will changes frequency up and down
Im using XCache for Template Cache (https://vborg.vbsupport.ru/showthread.php?t=139151&highlight=xcache) module without such problem! template vars are cached and they'r fetching as charm
but for datastore it s*x! sth wrong when cachin or probably fetchin

here is my xcache admin interface snaps which indicates what i wrote
76647
and here is my xcache configuration using 8 splits due to SMP CPU ( Clovertown Quad Core )
[xcache]
xcache.shm_scheme = "mmap"
xcache.size = 32M
xcache.count = 8
xcache.slots = 16K
xcache.ttl = 0
xcache.gc_interval = 0

Ofcourse You can, theres no relationship between PHP Output handlers (GZIP or Deflate) and PHP Opcoder/Variable cachers ( XCache or APC or eAccelerator )

Ok I solved the mistery. I spoke to the machine admin (I run the forum but I avoid messing with server configuration for I am no linux expert) and he told me that he compiled xcache without var cache support. He thought it wasn't necessary.

We will recompile in a few days. I'll update you guys then.

IrPr! You should increase the memory for op code cache. OOMs (out of memory) is no good. Try using 64 MB & see if there are any OOMs.

IrPr - Make sure the OOMs disappear.

Amenadiel - Double check that you have proparly uploaded the class_datastore_xcache.php & edited correctly class_datastore.php & config.php

Amenadiel

03-15-2008, 12:29 AM

Already did. Perhaps it's a problem of file permisions... perhaps I should set datastore_xcache as an exception in lighty in order to avoid being redirected by vbseo?

where is class_datastore.php being called? I can't see an entry in config.php, just

$config['Datastore']['class'] = 'vB_Datastore_XCache';

must I enable datastore caching somewhere in config or admin panel?

Anyway, why not install memcached or file based datastore?

Hey guys,

I have xcache installed on the server as a whole, and it sped up my forums greatly. Page loads went from 5-8 seconds to under 2 for the vbulletin areas.

Would installing this hack (Im on pre 3.6.X) for the datastore, provide an even greater increase to speed, load, etc?

I have a pretty busy forum with some heavy scripts running along side (multiple G2 galleries, etc etc). So if I can reduce further the forum needs, those other scripts might speed up too.

Just wondering if applying this to datastore is worth it if it is already kicking ass on a PHP level.

Thanks!

How to install the X-Cache under Windows?

I just found this INSTALL File with this text in it:

# vim:ts=4:sw=4
Installtion:

$ phpize --clean && phpize
$ ./configure --help
$ CFLAGS='your cflags' ./configure --enable-xcache --enable...
$ make
$ su
# make install
(update php.ini, restart php)

Reinstall:

$ mv config.nice conf
$ make distclean && phpize --clean && phpize
$ mv conf config.nice
$ ./config.nice
$ make
$ su
# make install
(update php.ini, restart php)

Update php.ini:
$ su
# cat xcache.ini >> /etc/php.ini
# $EDITOR /etc/php.ini

I cant explain what to do :D

Please somebody help me with 3 questions:

I have 512Mb on my dedicated. Is it right to make:
xcache.size = 64M
xcache.var_size = 64M
?
I have a Template Cache 0.0.4 installed and not sure about the size of xcache.

Do I need to enable xcache.optimizer? Default it is in Off state. Do I need to make
xcache.optimizer = On
?

I have a Fedora 7 installed on my server.
Is it better to make xcache.so in xcache.ini installed as a zend_extension or php extension? I have "extension = xcache.so" uncommented.

By the way, here is my phpinfo http://www.ulver.com/info.php
Thanks in advance.

hydn, is it possible for xcache and memcached to co-exist? If I have xcache installed as an oppcache, how should I install memcached?
Yes. It is. operation code and variable cache are two different things. If your database and web server are on the same box I would recommend you use xcache for opcode & datastore. If on separate boxes then use memcache for datastore of vb install on database server and xcache will run as usual on web server.

hope that helps.

Fenriz

04-15-2008, 11:41 AM

Ok, thank you. My database and web server are on the same box, so I'll continue to use xcache for opcode & datastore.

hydn

04-15-2008, 12:29 PM

In IIS zend conflicted with xcache for me. If it works for you use it. But not necessary. If you do use it benchmark because i'm not sure it will make things faster with xcache.

You don't need this plug-in in 3.7 because 3.7 already have this. You just have to enable it in your config.php under the ****** DATASTORE CACHE CONFIGURATION ***** option. Just type $config['Datastore']['class'] = 'vB_Datastore_XCache'; & save it.
