A few days ago I noticed the average load on a newly setup VPS was too high relative to its workload. The server was noticeably sluggish. Load was high and a page the wiki it was running would occasionally take 10 seconds to load.

I didn't have too much time to kill but I decided I would at least try picking off the lowest hanging fruit before upgrading to a beefier, more expensive plan which would cost a few hundred dollars extra a year.
