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)

lazee, are you saying vB Optimise 1.2.0 made it slower than 1.0.2, or that 1.2.0 didn't make as much difference ontop of what 1.0.2 already did?

As for flush cache, what cache method are you using?

As i see on my board the 1.0.2 reduce server load more than the 1.2.0 does .

The 1.0.2 server load never over 0.85 when my board pass 600 user and guest
The 1.2.0 server load get to 0.95 sometime spike over 1.00 when it 530 user and guest

I used Xcache for cache method.

[Deceptor]

lazee - Are you using the new cache options available from 1.2.0? Like the ability to cache homepage wol and datastore methods?

I'm unable to confirm 1.2.0 adds more load than 1.0.2, especially given the impact that it reduces queries and page generation time further. In either case, if your forum is that active, a change in load from 0.85 to 0.95 is minimal, and given the number of background processes a server does it'd be hard to tell if vB Optimise caused the extra 0.1 server load, you're welcome to test however, I'd recommend watching load over the next few days and seeing if there are any changes.

Also check out your vB debug info, to verify cache is working correctly, and queries are being reduced

Yes, i do cache homepage wol and datastore methods.

I will watch couple day and see how the load difference and and turn on the debug.

Btw, it help a lot at server load compare to before i install this optimize, thank you!

[Deceptor]

Gotcha, and I'm glad to hear that overall it is helping you, certainly the direction I'm aiming for here

[SBlueman]

I went to activate this modification and got this error:

Fatal error: Call to undefined method vb_activecache::connect() in /home/sblueman/public_html/forums/admincp/options.php(1027) : eval()'d code on line 93

[Deceptor]

SBlueman - Try this patch:

Open ./includes/class_activecache.php, Find:

	function set(){}

Underneath add:

	function connect()
	{
		return true;
	}

Save and upload, and try then. Overlooked this on my part, let me know if it works and I'll update the download

Have vb 3.7.4 + vbseo + memcached. Latest stable php + eaccelerator and so on...

Just enabled from admincp WOL=60 & refreshed main page. Other pages are ok.

Anyway, I'm not disapponted. WOL feature is not critical. Now vboptimise effect is not noticeable at my site, but will have to wait for middle of monday to compare.

[Deceptor]

Vitaly, if you disable vBSEO and enable the homepage WOL, does the error go away at all?

[SBlueman]

Looks like it saved....now.....what do I need to do to see if it's working properly? I am at http://gridironfans.com/
