Tips and Techniques for High Performance bitweaver

Created by: spiderr, Last modification: 24 Feb 2006 (22:00 UTC) by spiderr

Apache

Make sure you have an Advanced Apache Configuration for High Traffic Sites

PHP

Installation of a PHP opcode caching mechanism like php-eaccelerator ( which is a maintained version of turck-mmcache ) will dratically reduce PHP memory usage and improve execution time. It is available as a yum installable Fedora extra rpm.

Postgres

Install the tablefunc contribution to achieve massive optimization of GatekeeperPackage security look ups. tablefunc has the Oracle'esque "connectby" function that will let you execute recurisve queries on a hierarchical table that has id/parent_id rows, ala the tiki_fisheye_gallery_map. To install, make sure you have installed teh postgresql-contrib rpm/deb/whatever, and execute something like this FedoraCore 3 command line:

# psql foo < /usr/share/pgsql/contrib/tablefunc.sql

Then to your config_inc.php, add:

<?php
define
'POSTGRESQL_CONTRIB'TRUE );
?>


Areas to investigate for Code Opimizations

  • ADODB
If writing code, see the Tuning tips and install the ADODB C Extension
