Board Optimization - [DBTech] vB Optimise 2.0.1 (Lite)

vB Optimise Lite

This is ported from my original version released for vBulletin 3.8 located here. In this release I have re-coded vB Optimise from the gound and focused stability over features.

Professional version & feature list available @ www.DragonByte-Tech.com/forum
Priority support for Lite version is handled at the Developers Website.


What does it do?

vB Optimise is intended to optimise vBulletin software by integrating several PHP "cachers" and handling data before vBulletin. This works by encountering and handling data prior to vBulletin in order to skip the arbitary execution that would be more server intensive.

Real-Life Statistics

We've teamed up with some Big Forums to show you the impact of vB Optimise, you can view this public chart which shows both our statistics and theirs:

Features - Lite

• Supported Extensions
  • APC
  • eAccelerator
  • Memcache
  • XCache
  • WinCache
  • Filecache
• Style Cacher
  Caches style data to globally reduce a query within all vBulletin forum-based pages.
• Template Cacher
  Caches template data to globally reduce a query within all vBulletin forum-based pages.
• Datastore Cacher
  Forces custom datastore items from modifications (including those from vB's blogs) to use your configured Datastore Cache method instead of being forced into the database. This reduces page queries by where affected.
• vB CMS Template Caching
  (Automatic) Corrects many uncached templates within vB CMS to reduce upto 20+ queries on CMS pages (number varies based on content).
• Optimal Settings Check
  Provides a quick interface to identify possible settings which can be changed on your forum for further optimisation.
• Self-System Tester
  Provides a relatively straight-forward system check to ensure your vB Optimise installation works fully.
• Automatic Cache Flusher
  Automatically flushes cache within the Admin CP based on specific triggers to make sure content does not remain stale on your forum.
• XCache Authentification
  Supports XCache Admin Authentification by allowing you specify the username/password in a configuration if needs be.

Features - Pro

• Notices Cacher
  Caches users dismissed notices to reduce a near-global query within all vBulletin forum-based pages.
• Showgroups Cacher
  Caches the showgroups query which becomes more intensive as your user-base grows.
• Forum Display Query Enhancement
  Enhances a stock vBulletin query within Forum Display to speed up the page.
• Forum Home WOL Cache
  Caches Forum Home "Who's Online" to remove an intensive query and allow larger sites to display this data without impact.
• vB Cache Override (Feature not available on vBulletin 3)
  Ability to override vBulletins new built-in database cacher for the CMS / Forum Sidebar Blocks to remove anything from 1 to 20+ queries based on your content.
• Full Guest Caching
  Ability to cache entire pages and serve them saving not only hundreds of queries but upto 90% of CPU processing towards Guests.
• Statistical Resource Savings
  Ability to see just exactly how many queries per day vB Optimise has saved your database. You'll be surprised at the numbers.
• Forum Resource Statistic
  Shows off vB Optimise resource saving statistics directly within forumhome statistics.
• ....and more!

Release Notes

If you've used vB Optimise before you'll be aware the previous version had phrase caching, however this caused complications with the way phrases are used within vBulletin so it has not been ported over at this time.

FAQ

Q: I have WinCache installed, but vB Optimise tells me it's not?
A: WinCache only introduced OpCode support in version 1.1, if you're using version 1.0.x you will need to upgrade.

Q: I'm using the XCache method, flushing doesn't work?
A: If you have XCache authentification, turn the admin option on within vB Optimise Settings, then edit ./vboptimise/config.php and specify your XCache username/password. Alternatively you can disable XCache authentification within php.ini:

xcache.admin.enable_auth = Off

Q: I have eAccelerator installed, but vB Optimise tells me it's not?
A: eAccelerator does not provide the caching extension by default, you will need to recompile PHP with additional flags. For more information read eAccelerator documentation located here: http://eaccelerator.net/wiki/CompileConfiguration (Specifically look at: with-eaccelerator-shared-memory)

xcache much faster for me i don't want to use memcache
can you please say me waht is the best xcache configuration for Intel(R) Xeon(TM) MP CPU 2.80GHz

[Deceptor]

XCache isn't much faster actually, my benchmarks have shown at best it uses a little less runtime memory because it doesn't require a socket connection.

As for best configuration, I'm afraid I can't help you there, as far as I know there's no "good" configuration for XCache, if it's working it's fine

[Super Jinni]

Hi Deceptor,

I just installed your mode after installing XCache. But I'm having the same problem as rajubd.
When running the test I get this results:

Running Test: Connection to xcache
Test completed successfully
Running Test: Store Cache
Test completed successfully
Running Test: Fetch Cache
Your Opcache Operator extension is functioning, however it is unable to store data. Please check your extension configuration.
Running Test: Flush Cache
Test completed successfully

I've checked all the configuration of the xcache.ini file and here you are the contents:

; configuration for php Xcache module

[xcache-common]
;; install as zend extension (recommended), normally "$extension_dir/xcache.so"
zend_extension = /usr/lib/php5/20090626+lfs/xcache.so

[xcache.admin]
xcache.admin.enable_auth = Off
; Configure this to use admin pages
; xcache.admin.user = "mOo"
; xcache.admin.pass = md5($your_password)
; xcache.admin.pass = ""

[xcache]
; ini only settings, all the values here is default unless explained

; select low level shm/allocator scheme implemenation
xcache.shm_scheme =        "mmap"
; to disable: xcache.size=0
; to enable : xcache.size=64M etc (any size > 0) and your system mmap allows
xcache.size  =                16M
; set to cpu count (cat /proc/cpuinfo |grep -c processor)
xcache.count =                 1
; just a hash hints, you can always store count(items) > slots
xcache.slots =                8K
; ttl of the cache item, 0=forever
xcache.ttl   =                 0
; interval of gc scanning expired items, 0=no scan, other values is in seconds
xcache.gc_interval =           120

; same as aboves but for variable cache
xcache.var_size  =            16M
xcache.var_count =             1
xcache.var_slots =            8K
; default ttl
xcache.var_ttl   =             0
xcache.var_maxttl   =          0
xcache.var_gc_interval =     300

xcache.test =                On
; N/A for /dev/zero
xcache.readonly_protection = On
; for *nix, xcache.mmap_path is a file path, not directory.
; Use something like "/tmp/xcache" if you want to turn on ReadonlyProtection
; 2 group of php won't share the same /tmp/xcache
; for win32, xcache.mmap_path=anonymous map name, not file path
xcache.mmap_path =    "/dev/zero"


; leave it blank(disabled) or "/tmp/phpcore/"
; make sure it's writable by php (without checking open_basedir)
xcache.coredump_directory =   "/tmp/phpcore/"

; per request settings
xcache.cacher =               On
xcache.stat   =               On
xcache.optimizer =           On

[xcache.coverager]
; per request settings
; enable coverage data collecting for xcache.coveragedump_directory and xcache_coverager_start/stop/get/clean() functions (will hurt executing performance)
xcache.coverager =          On

; ini only settings
; make sure it's readable (care open_basedir) by coverage viewer script
; requires xcache.coverager=On
xcache.coveragedump_directory = "/tmp/pcov/"

It will be appreciated if you can help with this.

Edit: BTW, I'm on 3.8.5

Regards!

Configuration seems fine, as I told rajubd you might need to contact XCache on their support forums to see why it isn't working, it's a fairly common problem. If they point out what was wrong I'd love to hear what it is

[Super Jinni]

OK, I'll try to get in touch with them, in the meanwhile, what would you suggest to use as an alternative to XCache? I mean what do you think is the best to use along with vb forums? I'm sure you have a lot of experience in this field so I'd like to hear some suggestions from you.

Another question, can I let XCache running/working and use another opcache operator beside it like memcached or APC?

Thanks

[sadiq6210]

when I click on (System test) in admincp, I got this message
vB Optimise is currently offline. Please enable and configure vB Optimise to run a system test.

Although I enabled it from (admincp >> vB Optimise Settings)

[Super Jinni]

I uninstalled XCache and installed APC instead, but still getting the same result when running the test:

Running Test: Connection to xcache
Test completed successfully
Running Test: Store Cache
Test completed successfully
Running Test: Fetch Cache
Your Opcache Operator extension is functioning, however it is unable to store data. Please check your extension configuration.
Running Test: Flush Cache
Test completed successfully

I'm running CGI/FastCGI by the way (if that might have something to do with the issue).

Or is it possible to be a folder/file permission related problem?

Thanks for your help ^^

do you have an OpCode cacher installed? One of the ones mentioned like xcache, memcache, APC, etc....

what operating system are you using?

Also saw you were running 3.8.5 for VB, why aren't you using the 3.8 mod?

I'm using Ubuntu 10.04 LTS.
I'm also using the 3.8's mod.
When I was searching about my issue I got to this thread and found the same issue was already reported. So I thought I'd post it here.

I also thought this issue is related to XCache only, but now it's exist with APC.

[Deceptor]

Super Jinni - Best alternative to XCache in my mind is Memcache. In regards to your issue it may be a CGI/FastCGI issue, do you know if you're using DSO or SuPHP for the handler? Typically cPanel let's you choose when building apache/php from within WHM.

Memcache would resolve the issues because it's different from your typical opcode cachers, it runs as a dedicated service

sadiq - Make sure vB Optimise is online and you have selected a cache system to use, with no cache system selected there's nothing to test
