My site is performing badly, where it wasn't before. This is probably due to an increase in usage. The problem is visibale now that are school had to switch to distance learning again.
I've contacted my host to find out where the bottleneck is.
He says he's seeing al lot of empty http post requests, originating from ajax. The requests are originating from the same ip's.
Any idea what part of Moodle could be causing this? I do remember the 'chat activity' which I deactivated because it crashed my site. That was written in Ajax.
Any ideas of what I should be looking at or for are appricated.
