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)

I got someone real nice helping me with xcache so all my problems should be done after that....Thank you for your help if i wasn't broke i would def make a donation you deserve it.

[MissKalunji]

* never mind *

[MissKalunji]

something else. When vboptimize is enabled. If someone receive an e-mail from me

it shows as - instead of dancehallareaz.com Entertainment

When i disable it it shows fine...

Any ideas on what settings i might have messed up?

[KevinL]

If you search in the thread I think the answer was to disable caching phrases for the time being.

[MissKalunji]

oops sorry.

[KevinL]

haha no need to be sorry

I had to do it earlier myself

I am running a fairly busy forum at http://www.babyboom.pl/forum . We are currently running on two servers - one for web and a separate one for db.

On web server we are running nginx serving static files and proxying to apache2 with mod_php 5.2.3 and apc 3.0.19. On db - mysql 5.0.51.

The extension caused:
- a slight decrease in pageload (but hardly visible) and not consistent (some pageloads were longer some shorter),
- huge decrease in db->web bandwidh usage (from 30mbit avarage to 10mbit), but not that impressive drop in overall queries/sec numbers.
- noticeable increase in web server load (it's probably no more than few percent avarage cpu usage, but that pushed it over the limit in my case.

So far I have decided to turn it off because my web server is on it's last legs because of load (>900 concurrent users). I will resume tests when I install my new machine.

Thanks for your work :-)
It may have great influence in most situations, especially on sites where mysql is a bottleneck. But before you install, you have to consider a slight increase in load with APC...

vB Optimise: Your XCache requires administration authentification to be able to clear to cache, to login simply try flush the cache again. To disable admin authentification for XCache set "enable_auth" to Off in your php.ini configuration.

xcache.admin.enable_auth = Off

I'm a novice on Cache.

How can I identify my Cache Method and how can I change it?

Run php info (you can find it in the admin control panel at the very bottom in the "Maintenance" section. Scroll down and look for XCache and/or memcache. I'm not as familiar with eAccelerator or APC but they would likely appear there as well.

In order to configure vBulletin to work with the installed cache you would need to edit includes/config.php. The line is near the bottom and will look like:

$config['Datastore']['class'] = 'vB_Datastore_ XXX';

where XXX is the method that you use.

If you are on shared hosting you should provide a "datastore prefix" with the line:

$config['Datastore']['prefix'] = 'ZZZ';

where ZZZ is some prefix that will identify your items in the cache.

If no cache methods are available and you are on shared hosting you can ask your host to install XCache for you.
