Performance settings

Various performance settings can be changed by an administrator in Administration > Site administration > Server > Performance.

The setting "Maximum time limit" lets you restrict the maximum PHP execution time that Moodle will allow without any output being displayed. If you have a front-end server with its own time limit, set this value lower to receive PHP errors in logs.

config.php settings which may affect performance

Increasing the value of CONTEXT_CACHE_MAX_SIZE may reduce the number of database queries for certain pages. It will also increase memory usage, so be careful.

// Moodle 2.3: Increasing this from the default saved about > 1000 db queries on the course/index.php page for 
// a Moodle having 1250 course categories.
// This value is specified in lib/accesslib.php, but it's OK to add a define for it in config.php:
define('CONTEXT_CACHE_MAX_SIZE', 7500);
