ADODB 0.24 - Advanced Database Performance Enhancement

ADODB is a PHP library available from sourceforge, this is not to be confused for the PHP Extension ADODB they are too seperate things. There is of course a major bottle neck in the current database library where this patch will improve performace upto 1000% with XOOPS 2.3, XOOPS 2.4 & XOOPS 2.5.

It has been awhile coming and we will have some benchmarking for you in the next day or two we are currently running the tests on our Blade Server with 16Gbs of Memory which has minimal load to get an accurate respository of exactly how ADO Db performs in the XOOPS Classes.

To install this simply download the files and replace them in the directory tree class folder.

Download: xoops2.5_adodb_0.24.zip
Sourceforge: xoops2.5_adodb_0.24.zip
Demo: http://xoops.demo.chronolabs.coop

Some Benchmarking: (A Full Report is available below in spreedsheet)

Note: This bench testing is done on a shared Blade Server with 16GB used for IPTV, potentially the figures have been thrown by the occassional load on the server from crons and other system tasks; some of this testing is not direct database injection but instead using the XOOPS Classes Structures to better enhance the code execution testing
