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)

eAccelerator is set to use both, shared memory and disk (default). Maybe I should set it to "shm", which causes eAccelerator to use the disk only if the shared mem is full?

I'm no real expert on eAccelerator sadly, so I'm not sure if this would solve the rare case. It may even be a bug with eAccel but I can't be sure on that. If you change the setting and it doesn't occur again then I'd say it's worked, but it might be a cat and mouse game with trial and error unfortunately.

Hi Deceptor,

[mute]

Really, really looking forward to seeing this picked back up again!

I'd set it to "shm_only", once you determine the optimal size of shared memory so all scripts and cached keys fit in it. I'd start with 96M, and then watch the shared memory utilization in the eAccelerator control panel.

It happend again after submitting the changes to a usergroup. And if I remember correctly, I did the same when it happend the last time!

[Deceptor]

vB Optimise doesn't directly tie in with usergroups anywhere. The only cache it will potentially handle is Phrases (if you have Phrase Cache on and haven't disabled phrase cache in the ACP), and also handle custom datastore items. Nothing is actually "set" on this page unless those phrases/datastore items aren't already cached.

If you change the usergroup all the time will the error come up every time, or just some of the times? Also try removing the affected PHP line or comment it out and see if it rectifies the issue, as said before the function isn't required.

Good to see you back Deceptor.

[Adult SEO]

Is this mod usable for bigger forums, with 500.000 visitors per day? Or is there a turning point somewhere when the traffic is going up further?

[MentaL]

Nothing is storing in forum/vboptimise, any idea why?

[Sayid]

This is my best mod

most of options work but when I enable vB_Datastore_Filecache and the vB Optimise: Custom Datastore Cache, I got the following error in ACP :

Fatal error: Could not obtain file lock in ..\vb\includes\class_datastore.php on line 807
