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.

Thanks for the tip for:

PHP Code:


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

I use this hack for the cron:
https://vborg.vbsupport.ru/showthread.php?t=123719

Maybe you should give a try because it doesn't seem i have any cron issues...

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 just installed xcache and my boards are running smooth and fast.

I will install this hack once all the bugs have been fixed.

They are fine for me.

That's very interesting since the xcache website says it does not support the command line interface at this time.

Maybe we are still talking about the different things but whatever :) Peace...

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. :)

i m also getting this error
Fatal error: Class vb_datastore_xcache: Cannot inherit from undefined class vb_datastore in /home/forum/public_html/includes/class_datastore_xcache.php on line 14

i checked the answer of phpxcache regarding this error but unable to do. Please guide me.

I am running memcached here. Can I use both or they are mutual exclusive? Anyone made performance tests comparing the two?

Thanks

haven't used memcached but just installed xcache/datastore hack on one of my forums.. made a tremendous difference to the speed :D

excellent stuff !

anyone have any ideas how this would work with load balanced multi web server setup ? guess memcached would work better for load balanced servers ?

I use memcached on my setup, I have two webservers and I installed memcached on my MySQL server, so the memcached on MySQL server caches for both webservers.

you can use XCache as opcode cacher, while using xcache OR memcached as vBulletin datastore cache.

Can you explain how?, I'll installed the Xcache hack, and It will Cache the php files?, can someone explain what do you mean by "datastore"?

how can I work with memcache and Xcache to get the most out of the two of them?
memcache will cache the DB ( how exactly ? ) there is another hack?
and the Xcache will cache the php time? and the php process time will be faster?

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.

beside of that, What do you think will do the work better Xcache with this hack or Memcache?
Are they doing the same things?

There is DC caching and PHP caching, What do I use Memcache for?

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.

What is the lowest I should set my var.cache size?

Would it be foolish to set it to something as low a 4M? I ask because after running it for about an hour I only used around 2mb of the cache and it was showing no signs of maxing out.

Paul M

07-01-2007 06:37 PM

4M is plenty if you are only using it for vbulletin (I only have mine set to 2M).

Are you planning to release a modification that will work with Xcache / memcache and will cache php too?

Thanks a lot.

If you want real performance, yes use both of them, but do not enable xcache in config.php file.
More exacly, use memcached for datastore and XCache for the php files.
I built my own rpms, optimized for lighty and vbulletin. Please dont ask me anything if you use Crapache. :)

I have installed this modification, and nothing is changed..
how can I Be 100% that this modification is doing some thing? :\
Maybe I havn't installed it property , but there isn't anything to do, upload a file and to add a line in the config file..

what may be wrong?

config file -

PHP Code:


		
			
    // Here you can configure different methods for caching datastore items.

    // 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

//$config['Datastore']['class'] = 'vB_Datastore_Memcached';

//$i = 0;

// First Server

$i++;

$config['Misc']['memcacheserver'][$i]        = '127.0.0.3';

$config['Misc']['memcacheport'][$i]            = 11211;

$config['Misc']['memcachepersistent'][$i]    = true;

$config['Misc']['memcacheweight'][$i]        = 1;

$config['Misc']['memcachetimeout'][$i]        = 1;

$config['Misc']['memcacheretry_interval'][$i] = 15;

class_datastore -

PHP Code:


		
			
        }

        return true;

    }

}

// add class_datastore_xcache, enable it in config.php

require_once(DIR . '/includes/class_datastore_xcache.php'); 



/*======================================================================*\

I've uploaded the class_datastore_xcache.php to /includes/class_datastore_xcache.php

I'm pretty sure you will want to comment out the $config['Misc']['memcache* lines if you want to switch to xcache.

sure, rpm won't run for you, but it will install xcache, and you run php+xcache. that's it. it doesn't matter if you install it with rpm or whatever

u have to get your XCache run first.

i suppose u have installed a XCache with rpm, but u shall append php.ini with xcache.ini and update some values.

see http://xcache.lighttpd.net/wiki/Inst...AsPhpExtension

As for installing it, I don't really recommend it. I've found it to be somewhat
buggy, and doesn't work well with ionCube, or Zend Optimizer.

as I'm running Zend, I don't want to install xcache if it's going to crash the site.
any comment is greatly appreciated.

This is true with the previous versions of XCache, but not the current versions (to my knowledge).
