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)

If I work on a user and then stores the following mistake comes Like does repair I this? Sorry my English is not so good

PHP Code:

Fatal error: Call to undefined function print_cp_message() in /var/www/vhosts/rheuma-treffpunkt.at/httpdocs/forum/vboptimise/core/class_operator_eaccelerator.php on line 50

Hi Ronny,

The PHP error is a bug, however the line it has invoked means your using eAccelerator and it's not configured correctly to allow flushing. The message should say:

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 http://bart.eaccelerator.net/doc/php...elerator_clear

Once that's resolved, the error shouldn't occur anymore.

I'll get the error patched in the next release regardless

[Ronny46]

Thank you for the answer, so is called I must wait for the next version?

[Deceptor]

Hi Ronny,

The update will resolve the error, however the actual problem is that vB Optimise cannot flush the cache because eAccelerator requires you to set permissions to the script path, without that done vB Optimise will not function correctly (your data will become stale).

[Deceptor]

I've released the 1.6.1 update Ronny, it will remove the PHP error as I discussed but your eAccelerator still needs to be configured or flushing won't work.

Any chance wincache support can be added for the 3.8 version?

The 3.8 version is discontinued unfortunately, due to issues and as such some elements being cached in the vB4 version don't exist in vB 3.8 (atleast within Pro, which may trickle down to lite).

That said, adding the WinCache support is relatively easy, you'll need to do two things. Firstly, open ./includes/class_activecache_methods.php, then add this lump of code right above the last "?>"

PHP Code:

class vb_activecache_wincache extends vb_activecache
{
    static $class = __CLASS__;
    static $instance;

    function get_instance()
    {
        return (self::$instance) ? self::$instance : (self::$instance =& new self::$class());
    }

    function suicide()
    {
        if (self::$instance)
        {
            self::$instance = null;
        }

        parent::suicide();
    }

    function connect()
    {
        if (!function_exists('wincache_ucache_get'))
        {
            return false;
        }

        return true;
    }

    function set_title(&$title)
    {
        $title = $this->prefix . $title;
    }

    function fetch($title)
    {
        if (!$this->connect())
        {
            return false;
        }

        $this->set_title($title);

        return $this->integrity_check(wincache_ucache_get($title));
    }

    function set($title, $item)
    {
        if (!$this->connect())
        {
            return false;
        }

        $this->set_title($title);

        if (trim($item) == '')
        {
            $item = '{_______VB_ACTIVE_CACHE_BLANK_______}';
        }

        wincache_ucache_set($title, $item);
    }

    function flush()
    {
        wincache_ucache_clear();
    }
} 


Secondly you'd need to add the option for WinCache in the options, you can do this one of two ways. If you have debug mode enabled, you can simply edit the option within the ACP. Or if you want, you can edit the product XML and find the following:

memcache|Memcache
xcache|XCache
apc|APC

Simply change to:

memcache|Memcache
xcache|XCache
apc|APC
wincache|WinCache

Then re-import the product XML, you should get the option and it should work, although I haven't tested it
