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.
• 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)

any plans to support zend?

Could you elaborate please?

i thought zend optimiser was a php cache (that's what my webhosting told me) that's why i was asking.

Sorry

*sight*

[Deceptor]

Ah, Zend Optimiser you mean? It's to encode scripts mostly, but by encoding it makes them run a little faster, not what vB Optimise does exactly

no problem it's just a question very nice work

9 queries instead of 11. All as promissed

What cache method are you using?

- eaccelerator for php code, memcached in all vb settings.
- 500-600 online.
- ~0.9 sec for main page, ~0.3 for others.
- nginx + 6 php-fcgi + 1 mysql processes.

(*) WOL was off.

Anyway, your mod is a good example of clear coding and outstanding support. Such functionality MUST be included in vB by default.

If you know some trustable non sintetic methods to measure load & latency - i could try.

[Deceptor]

Vitaly - Your server seems setup so well that a change in page generation time would require some huge changes, the two queries reduced will probably just effect queries ofcourse, and internal bandwidth (especially if you use another server for your database).

As for measuring load and such, I'm afraid not. Still, it has had some positive impact on your forum

[dtv100]

any chance to have a box to write xcache login info to make this work even better?

this hack work really good .
thanks

[Deceptor]

dtv100 - I have considered this, but it may be unsecure. That said, I can place it in the next version purely as being optional

pay no attention to the data compiled for today the 22nd as it is not complete

I should include that last sunday's traffic (14th) was very similar to this sunday's (21st). I am using memcache. There is also a similar trend on the web server's inbound data.

Outbound bandwidth has decreased by ~47% on the database server!!! (based one day of similar data) What does this mean for most of you? Fewer database queries = lower server load = faster site = happy forum users!

Bottom line: This mod is going to save me money as I am currently going over on my bandwidth as well as improve user experience!

Nominated for mod of the month and will be donating

While I'd say this is certainly fantastic.... could it be the holidays, mostly? You should see a relative decrease in all traffic, CPU and RAM utilization, and so forth if that were the case.

I just can't imagine disabling 2-3 global queries has such a large impact... Esp w/ one of them being such a small query.. (The style one)

Of course if it continually stays that low, good work Deceptor!!

[Deceptor]

tmc - While I agree it could be holidays, the templates query is the largest query vB executes, so I would expect some impact. In anycase, it'd be nice to see the results over a longer period
