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.

  (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)

good, at times i have 700 members online with about 900 spiders, i have to turn off my plugin/ hook system so my forum does not lockup. using a VPS server. we will see what this does in a week when i get slammed again

[Deceptor]

You should recieve a prompt when attempting to flush the cache asking for your username/password, this is because your XCache is configured to require an admin username/password when using administrative XCache functions. Is the pop-up for authentification not showing?

This can be disabled through your php.ini:

xcache.admin.enable_auth = Off

[glorify]

Nope, not showing.

[Deceptor]

From what tests I've been able to do, the prompt should show on failure. It's possible the error haults this from happening, try the following change to see if it resolves your issue:

Open: ./includes/class_activecache_methods.php, Find:

		for ($x = 0, $total = xcache_count(XC_TYPE_VAR); $x < $total; $x++)
		{
			if (xcache_clear_cache(XC_TYPE_VAR, $x))
			{
				$any = true;
			}
		}

Change this to:

		for ($x = 0, $total = xcache_count(XC_TYPE_VAR); $x < $total; $x++)
		{
			if (@xcache_clear_cache(XC_TYPE_VAR, $x))
			{
				$any = true;
			}
		}

Find:

if (!isset($_SERVER['PHP_AUTH_USER']) && $x < 1)

Change this to:

if (!isset($_SERVER['PHP_AUTH_USER']))

Save and upload, let me know if this resolves the issue for you

Was able to get it using that workaround

Thanks. Didn't try the other lol.

[Deceptor]

No problem If you get a chance to try out the above changes to see if that works let me know how it goes.

[glorify]

I will, but I probably won't get the error now. Great work. Thank you. By the way, I am running RC1 and haven't upgraded to 2 yet.

[Deceptor]

Thanks for the note, it should run on beta installations of vB 3.8 too, but I won't swear by it

You'll be able to select styles correctly then

thanks works as promised

1 question -- when i try to flush, it asks me for xcache username and passwd, when i give the ones i have in php.ini file, it says wrong. wat are these username and passwd?

also vboptimize directory has only 1 index.htm file? am i supposed to 777 this dir so vboptimize can write some files here?

[Deceptor]

You need to specify your username and password for XCache, remember the password in php.ini should not be an actual password, but an md5 encrypted password, then you enter the plain-text password in the prompt. Otherwise you can disable the admin authentification for XCache, see a couple of posts above to see how.

As for vboptimise/, yes it should have read/write permissions, as specified in the Admin CP descriptions when you setup vB Optimise
