Hardware and performance

Issues related to computer hardware and Moodle's performance under load.

Documentation: Performance and Performance FAQ
Forum moderator: Howard Miller

Read this first!

This forum is for discussing issues related to computer hardware for Moodle, as well as comparing notes on Moodle's performance under load. Advice on finding an internet hosting service also belongs here.

Before posting your question here please read the documentation Performance and and Performance FAQ.

Many of the questions have already been answered. Please make use of the Advanced forum search and the Google custom search to find them.

If your questions still remain unanswered, post them here. Include as much background information as possible about your hardware - operating system, web server, database server, PHP scripting framework, etc. If your machine is virtualized, also mention the host hardware, operating system, virtualization technology used and resources assigned to the virtual machine. If you use a hosting service, mention either the hosting provider and the package or resources as advertised.

For general advice on how to ask questions, refer to the Moodle.org forums help. Also please observe our site policy.

Best wishes,
your moderator Howard.
