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

vB Optimise Lite

The newly revamped vB Optimise was created for vBulletin 4, but has now been made compatible for vBulletin 3.8. In this release I have re-coded vB Optimise from the gound and focused stability over features, you'll notice Phrase Caching and vBAdvanced Integration have bit the dust, this is to maintain a sync state between this version and the vBulletin 4 release.

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

• 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 is not compatible with Zend Optimizer (even confirmed by Cpanel level III analyst the other day).

Memcache is working now, but I'm wondering what does the graph mean by "misses"?

What's a good method of testing the results before and after?

I tried using eaccelerator, but I get the same error that its not active or installed, meanwhile it is compiled
and outputted in php -m

PS: thanks for the help

[KevinL]

Thats old...xcache works fine with zend now. I have it running just fine

Also misses are fine..you want to keep an eye out for OOMs (out of memory)

No worries any time.

[BeoRski]

chadi, you need to compile eaccelerator with the "--with-eaccelerator-shared-memory" option.

[Chadi]

Yes, I had done that based on below steps suggested by cpanel tech:

1) cd /var/cpanel/easy/apache/rawopts
2) touch all_suphp
3) nano -w all_suphp ( considering you are running SuPHP )
4) Within the file add per line the following:
--enable-eaccelerator=shared
--with-eaccelerator-shared-memory
--with-php-config=$PHP_PREFIX/bin/php-config

Likewise if you were only running DSO/CGI within PHP5 steps 2-4 would be repeated after touching and editing the file all_php5.

This would be all that would need to be in place so that Easy Apache would add the configured flags to your PHP build.

Recompiled and still does not work (although eaccelerator shows up in php otherwise, but the vb mod here is not picking it up)

I'm having an issue where some users are reporting that the CSS isn't loading for them in various styles sporadically since I installed this mod. I'm using XCache and have tried clearing the cache several times. I'm unable to replicate this issue myself unfortunately and can't pin it down to a specific browser.

Any suggestions?

[BeoRski]

chadi, I guess Memcache will have to do for you right now...

msu2k, it doesn't cache CSS files. Have you tried moving your CSS to the filesystem (if you haven't done so yet)?

Yes, the CSS files have been moved to the filesystem. Pages seem to be loading for people without any CSS files, then appear normal later. I can't seem to figure it out.

[briansol]

i'm using eaccelerator only (xcache just doesn't like my server.... ) no memcache, or anything else.
php 5.2.6, mysql 5.0.65-com

before:

vBulletin 3.7.2 Debug Information

* Page Generation 0.02674 seconds
* Memory Usage 4,640KB
* Queries Executed 9 (?)



After:

(1st load (obviously there is no cache yet...))

vBulletin 3.7.2 Debug Information

* Page Generation 0.52209 seconds
* Memory Usage 4,865KB
* Queries Executed 9 (?)



(2nd load)

vBulletin 3.7.2 Debug Information

* Page Generation 0.02992 seconds
* Memory Usage 4,865KB
* Queries Executed 7 (?)




the 2 query drop is nice, but it doesn't seem to have any effect on total performance

:shrug:

WOL cache messes up display of bots with this mod:

bots should show last
