Standard OPCache extension is strongly recommended since Moodle 2.6, it is the only solution officially supported by PHP developers. The benefits are increased performance and significantly lower memory use.

Installation

The OPcache extension is distributed as part of PHP 5.5.0 and later. It is available also for older stable PHP releases from PECL under the original name ZendOPcache.

Configuration

PHP.ini settings:

[opcache] opcache.enable = 1 opcache.memory_consumption = 128 opcache.max_accelerated_files = 4000 opcache.revalidate_freq = 60

Required for Moodle

opcache.use_cwd = 1 opcache.validate_timestamps = 1 opcache.save_comments = 1 opcache.enable_file_override = 0

If something does not work in Moodle
opcache.revalidate_path = 1 ; May fix problems with include paths
Experimental for Moodle 2.6 and later
opcache.fast_shutdown = 1
opcache.enable_cli = 1 ; Speeds up CLI cron
opcache.load_comments = 0 ; May lower memory use, might not be compatible with addons and other apps.
