VPS: CPU seams to be under heavy load while no process produces such load?

I recently set up a really cheap VPS mainly for backup purposes but I also wanted it to do some small, minor tasks. But because I was too interested I wanted to take a look at CPU and Memory usage, since I only got (probably part of) 1 Core of…

I am trying to find out ideal load average for one of my linux servers. I understood load should be proportional to the no of cpu cores. But my doubt is that, how will we analyze this in case of multi core CPUs? [root@server unnik]# getconf…
