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)

Going to keep an eye on this one

Is there any other way to fix this issue? I want to keep the most benifits of vboptimize...

But this problem I am seeing too, the people can't tell who sent the emails for registration.

For me (on 3.8.3), this only made a generation time and memory improvement (5-10 milliseconds) with cache styles and cache custom datastore.

Even though I have Xcache installed this option doesn't seem to work, so I had to use File Cache.

Caching templates actually slowed my forum by about 40 milliseconds.
Caching phrases added about 20 queries on every page load... so not using that.

[thincom2000]

Uninstalling this made an even more noticeable difference than 5-10 milliseconds.

Thanks and installed!

My forum is 2x the speed of what it used to be. Thank you so much!

I'm using this on my forum. Installed it during the week.
I am just using the WOL, styles and custom datastore cache (which I make heavy use of in some of my scripts ).

The phrase cache I've read is broken so I turned it off.

As for the template cache, I noticed that when I edit templates and save them they don't get updated in the cache. Any fix or this? I'm using eaccelerator.

Did you try flushing the cache after the change?

I found that the problem was that I don't have permission to use the flush function.
An easy way to fix this I found was to write my own flush function.

If anyone wants it here it is.
Line 359 in file class_activecache_methods.php is where the eAccelerator Flush function starts.
Replace:

PHP Code:

function flush($silent = false)
    {
        $success = '__vBOptimise_EA_Test_' . rand(3,999) . '__';

        $this->set('vBOptimiseTest', $success);

        @eaccelerator_clear();

        if ($this->fetch('vBOptimiseTest') == $success)
        {
            print_cp_message('vB Optimise: Your eAccelerator requires you to specify permission to this directory to allow vB Optimise to clear your cache. For more information please visit <a href="http://bart.eaccelerator.net/doc/phpdoc/eAccelerator/_info_php.html#functioneaccelerator_clear" target="_blank"></a>.');
        }
    } 


With:

PHP Code:

function flush($silent = false)
    {
        foreach (eaccelerator_list_keys() AS $cacheitem)
        {
            $key = ( strpos($cacheitem['name'], ':') === 0 ? substr($cacheitem['name'], 1) : $cacheitem['name'] );
            eaccelerator_rm($key);
        }
    } 


THIS IS FOR EACCELERATOR USERS ONLY

Does anyone want to tell me what exactly are all of the problems with cache phrases?
I can hopefully fix some or all of them to make this part of the hack useful for all.
Seeing as there's no support from the mod author...

One of the problems was that there would be no titles on emails sent from the forum. Cached phrases would not work with emails.

Also, on error pages, you have the site title at the top of the error box normally, with the cached phrases turned on there would sometimes just be a dash where the site title should be.
