vb.org Archive - Board Optimization - Datastore cache to WinCache

This allows you to use WinCache as a datastore cache in vBulletin. This also assumes that you have already installed Wincache version 1.1 or later. This is definitely your choice if you have already installed and enabled WinCache on your windows server. Use at your own risk!

(See screenshot of stats below after 30mins up-time)

Prerequisites

a working php installation
a working vBulletin 4.0.2 installation
a working WinCache 1.1 or Better.

Install the modification

Add the following code to the end of class_datastore.php just above "?>"

Code:

}

2. Set your config.php to use wincache for datastore:

Code:

$config['Datastore']['class'] = 'vB_Datastore_WINCACHE';

Done!

Check the "User and Session Cache" section of your wincache.php (screenshot) in your browser to see stats!
