MUC Stage 1: Implement some core caching architecture (MUC)

    XMLWordPrintable

Details

    Description

      A single new caching system that can be applied whenever a developer writes code that could benefit from a cache. This consistency will give the admin more flexibility to configure Moodle to cope with very large loads by saving CPU and I/O.

      The caching system allows the admin to choose from a variety of different backends, ranging from simple files to memcached and everything else.
