I am having performance issues with my 2.4.3+ moodle site. Users have complained and I have also noticed myself that it sometimes takes a very long time for the site to come up when you type in the URL (routinely over 20 seconds, at times over a minute without timing out). Logging in takes a similar amount of time. Once you are logged in it is usually quick, although maybe one time in ten a page will fail to load.
It confuses me that the site is sometimes really fast, but other times very slow. This happens on different browsers, OSs, user locations. It also occurs when there are no other users logged in. I have tried changing the theme also without affecting the problem. Our host suggested upgrading to most recent moodle which we have done, but the problem persists intermittently. Does this sound like an issue related to the server we are on?
Thanks for any thoughts.
