Hopefully you guys can give me some help. I am trying to host a site for a client and I have had nothing but problems after upgrade. Im using 1.5.2 on a Dual Xeon Server with 1 GB ram and plenty of hard drive space. The Moodle install will OFTEN slow down enough to be not usable when the server load is below 1. My server admin puts it:
"Well, the mystery about this site is that sometimes it runs very smooth and sometimes it loads initial page 10 seconds even though load is ok (below 1), there is RAM memory available and both apache and mysql aren't overloaded."
Any configuration changes you can suggest or possible reasons it may slow down would be helpfull.
