Moodle is running super slow

Moodle is running super slow

We've had Moodle for some time now and have always noticed that it loads fairly quickly.  We have people accessing the training on our Moodle site and now it seems to be operating very slowly, even on a DSL and LAN connection. 

Any ideas why this is?  I've sent a note to our hosting company to see if they could fix something. 

I'm not sure why it's slow now and it wasn't before. 

Thanks,
Angela

This happened on our website and I found that a semicolon had been deleted from a parameter in one of our cascading style sheets.

There are probably other simple reasons unrelated to your server, you might want to try using the browser Firefox <http://www.getfirefox.com/>; and check the JavaScript Console in the Tools menu.

Another possibility I have seen listed in a forum is that you may need to clean out old users from your database, if the memory is getting full.

Hi Sandra! Good advise on the CSS and Firefox, but watch out:

"old users" never affect performance. Memory tuning is important, however. I'd recommend heading over to the servers and performance forum, and searching for "apache tuning" 眨眼

If somebody else is hosting it then I don't know that there is much you can do assuming nothing has changed at your end. I take it you are not suddenly doing classroom quizzes with 100 students or suchlike.

If your hosts are any good, they should be able to quickly analyse the problem.

EDIT:
I have found that the RSS block is great at slowing things to a halt. Have you suddenly started using that?

Hi
Our moodle went slow because the mdl_log table had 1/4 million records - things went much faster when we moved them to another table

Just a thought
