Board Optimization - [DBTech] vB Optimise 2.0.1 (Lite)

vB Optimise Lite

This is ported from my original version released for vBulletin 3.8 located here. In this release I have re-coded vB Optimise from the gound and focused stability over features.

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 - Lite

• 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)

XCache may not work with certain PHP setups FFMania, it can be funny with FastCGI/DSO depending on the handler/module php is running under. In most circumstances I tell people Memcache would be a better option because it does not fall victim to PHP setups as it runs as a dedicated service.

ok and thanks for help. i am going to install the xchache as ur recommendation.

so now how i can configure the xchache and plz give me best xchache configuration setup.

my server processor : xenon 2.24 GHZ
RAM : 1024 MB
HDD ; 15 GB

coz i am new and i don't know how to configure xchache module and which sitting is best for my server.

thanks

Hi newsoftw,

With XCache all you really need to do is tweak the memory allocations to the cache and var cache, var cache is the only one vB Optimise is concerned with, for Lite I'd recommend allocating about 30M (which is 30MB) - should be more than enough, the other cache is for php files which XCache does automatically, you can assign that to whatever you like depending on how much php you have on your server, 30M there too should be a solid value.

No other tweaking needed really, although the configuration does ask for your cpu count and it does give you the command to run to find out, so make sure that's valid and you're all good

Is it ok, when my forum uses memcached itself, but vB Optomise configured to use filecache?

I am getting arrors while setting to use memcached, thats why use filecache.

[Deceptor]

What kind of errors Artak? Make sure you've configured memcache for vBulletin in includes/config.php, vB Optimise will use those memcache connection settings. After assigning Memcache to vB Optimise in the settings, run the System Test found under the vB Optimise menu in the ACP - this will make sure everything is operating correctly with the configured operator.

Memcahced is configured for vBulletin and working. But system test giving the following resylts

Running Test: Connection to memcache Test completed successfully
Running Test: Store Cache Your Opcache Operator extension is functioning, however it is unable to store data. Please check your extension configuration.
Running Test: Fetch Cache Your Opcache Operator extension is functioning, however it is unable to store data. Please check your extension configuration.
Running Test: Flush Cache Test completed successfully

[Deceptor]

That would mean it's not working then (even with vBulletin), vBulletin won't throw errors if the datastore cache you're using is failing to store/fetch, it'll just keep using the database and make 0 difference. The tests done by vB Optimise verify everything is working with your operator by executing the tests, as a means to identify if it is/isn't working and pin-point exactly what isn't.

I'd check to make sure your Memcached instance is running and running with allocated memory, if unsure it's best to ask your host.

[ArtakEVN]

OMG. You are right. sorry, the process was interrapted. Now everything seems ok.

this mod is fantasic
i heard even more good things about pro version
