Question

I'm running a website on a cloud server. The website is functioning completely around a (rather large) database. Over the last two weeks I've noticed steady rise in the CPU load of the MYSQL and I'm not sure why. It has been 15-16% for a while and then it started climbing by 1-2% a day. Currently we are at 27% and thought there has been a rise in traffic, it wasn't that big.... What could be causing this?

Thanks!

Was it helpful?

Solution 2

The problem actually was the build-up of several caches. If someone else encounters this problem, I suggest to look at the red values under 'Status'-> 'All statusvariables' in your PHPmyAdmin. Enlarging the tmp_table_size and flushing the query cache did wonders for me.

Good luck!

OTHER TIPS

Check you MySQL slow log. Don't forget to add the queries not using indexes in the log.

Fix any queries you find in there.
