Server load in Dashboard?
Using Jamroom
Linux's scheduler is really good - like Michael pointed out, any load over 1.00 means that processes are having to wait to receive CPU time, so you're going to get diminished performance. In Jamroom we show you the 5 minute load. The 1 minute load is going to go up and down a lot more, but the 5 minute is the average queue depth over the last 5 minutes - if that is constantly over 1 then it means the site could perform better if upgraded.
