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

• 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)

I'm using VBSEO 3.x, Can I use VB Optimise ????????
And ...
How do I know that I should use "Memcache" or "Filecache" ?????

[Deceptor]

vB Optimise is compatible with vBSEO, if there are any issues let me know

As for cachers, everyone can use "Filecache" (that's the most basic), as for Memcache/XCache/etc.., if unsure contact your host, generally these are not pre-installed so you may need one installing (I recommend XCache for typical setups).

I'm Using Kloxo server with ServerAPI: Cgi/FastCGI

[rsj1]

I would assume you're running a windows server from the location you have set up for your xcache dll (plus dlls are windows only). Koloxo is a control panel so doesn't tell us if you're running apache or not. However I would guess your problem is here:

xcache.mmap_path = "/tmp/xcache"

that's a linux filepath - fix it and restart whatever you use if it isn't apache and try again

If that doesn't help I would suggest going to the xcache site for support as this is certainly an xcache issue not a vbulletin/vboptimse issue

[Deceptor]

Pretty much what rsj1 said - XCache can commonly fail to "store" cache between sessions on setups which is one reason the System Test was created because outlining these issues is otherwise very had to visualise.

If changing the mmap_path or XCache support is able to resolve your setup issue it'd be great if you posted it here too incase others are experiencing the same issue

[Trana]

I installed this on IIS and received the following error when I try to enable it:

vB Optimise: You have selected a cache method that vB Optimise has detected you cannot use, this may be because the extension required is either not installed or configured correctly on your server. Please contact your system administrator or hosting provider for more information.

I am using Wincache and according to phpinfo it is enabled:

wincache
Opcode cache enabled
File cache enabled
Version 1.0.1325.0
Owner iisphp@microsoft.com
Build Date Jan 21 2010 17:35:42

Any ideas what I might have missed?

[Deceptor]

Trana - WinCache added var cache support in 1.1, you're using 1.0 (however note WinCache 1.1 is in beta). This is covered in the FP FAQ:

[jrap]

Fantastic product, thanks so much!

[nascartr]

I've gotten my host to enable eAccelerator but now when I try to flush the cache I get this error.


vB Optimise: Your eAccelerator requires you to specify permission to this directory to allow vB Optimise to clear your cache. For more information please visit here.

[Deceptor]

Hi nascartr,

eAccelerator can be configured with protection, as such it requires you to manually give scripts permissions to access certain functions (in our case the flush). You or your host will need to edit your php configuration for eAccelerator and specify the location to: /your/path/to/forums/vboptimise/core/core_vboptimise.php within the setting eaccelerator.admin_allowed_path.

Seems silly I know, but that's eAccelerator for you
