More on high CPU utilitzation
Thanks for the answers, everybody.
The thing is, I don't have a problem with memory utilitization. It is really CPU utilization. After login in (I use Gnome), the CPU immediately at 50%.
Somehow I was hoping, that on a 2000 Mhz Athlon 64, linux would be running like a dream. But it really doesn't, so I would like to optimize it. But I don't know how to determin what eats up half of the CPU
