I've been noticing some random slow downs over the last few weeks and today I contacted by hosting provider to find out what was going.
What would happen is the site would get extremely slow or just stop loading for a few mins, then be back to normal. I had originally thought it was a network issue with my host, but they've had none.
When they looked into it they saw that mysql was the problem and looked for the slowest processes which turned out to be all from the credits plugin I'm using.
Below is one example, but there were about 20 of these listed. Each with different userID, but all with about 20-30 seconds query times. It seems these are randomly causing huge CPU spikes and either slow down the entire server or stop the site from loading all together.
credits_transactions is that the process for when someone earns 'credits' for doing something on the forums? Any idea on how to fix this?

SET timestamp=1361547931;
SELECT t.* FROM credits_transaction AS t LEFT JOIN credits_event AS e ON (t.eventid = e.eventid) WHERE t.userid = 184613 AND t.status = 0 AND (e.eventid IS NULL OR t.timestamp <= (1361547909 - e.delay)) ORDER BY t.timestamp ASC LIMIT 1;credits_transactions is that the process for when someone earns 'credits' for doing something on the forums?
