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.

• 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)

Just let me say I got this working, after a lot of messing around with eAccelerator (which is NO fault of this mod, damn server side caching stuff is just a pain). Even without eAccelerator and just using the file cache and optimized settings the mod recommends we saw performance gains. Now, it's lightning fast.

I recommend this to anyone, it's worth the effort.

I am still seeing odd caching issues, but mostly due to mods that don't handle cache properly (including some of my own - soon to be fixed).

Great work.

My board is new, no users yet, but want it to be FAAST! Installed and thanking!

When I create a new profile field , the title of the profile doesn't display !

Disabling vB Optimise cache phrases fixes this issue, any ideas?

[KevinL]

Keep cache phases disabled might be the only way...

Even after flushing the cache?

[Sayid]

Yes

[Tauhid]

installed, so far no complaints!

[sall]

Installed, template and style caching seem to be working fine
VBA module caching is not.

vbOptimize is enabled.
Using 'file cache' method.
VBA integration enabled.
The VBA modules I want to cache are marked as 'Yes' and '60' seconds.

Using vbulletin 1.8.0 vboptimize 1.3.2 vbadvanced 3.1

The caching for the modules is just not working. No error messages on debug mode either.
Any ideas on what might be going on?

[Sayid]

You have to note that the title of the previous fields work and appear without problems but when I create a new one , it doesn't display .
Anyone tries to test if the same bug appears in his forum ?

thanks in advance

I think I already said I love this mod, but I'm saying it again.

I've been working support for it into my own mods, and learned something worth sharing that the example modification pointed to by the author doesn't cover:

You have to invalidate your own cache. It's easy enough to do, just set it to blank and the mod takes care of it for you, but things won't work if you don't.

As an example, if you are caching the eggs that are on an avatar, when someone throws a new egg at said avatar you have to invalidate the cache for that query or the new egg will not show up.

It's important when writing support for this mod that you consider all your invalidation scenarios.

Also, you cannot invalidate vBulletin data (without a lot of work I assure you that you do not want to do). So if you have a query that, for example, gets the users last login date, you can't cache that. Fortunately vbulletin does it's own cache to some extent, and vb Optimise does more, so just hope for the best on volatile vBulletin data. It's out of your hands.

PHP Code:

$optimise->set('mycachekey', ''); 


Is all that's required to invalid cache. 'mycachekey' of course being the key to the cached item you need to invalidate.
