Fixing Moodle Slowness

Occasionally, Moodle starts to misbehave and respond much more slowly than it has previously.  This is most likely to be experienced when you have been doing a lot of work in Moodle recently, so often it is a problem at the beginning of the term.

Most of the time, this slowness is related to your browser keeping local copies of the Moodle pages which eventually get somewhat corrupted.  Try these things to counter-act this problem.

Delete Browsing Data

You may be familiar with this tactic with other websites, and it's a good trick for when websites do not work as expected.  Check out this ITS Knowledge Base article about how to do this in the various browsers you may be using.
