50% CPU utilization on AMD 64, with 64 bit Fedora Core 3

bh2005 · 04-25-2005, 10:55 AM

I have recently installed the 64 bit Fedora Core 3 on an machine with AMD 64 Athlon processor. It looks rather strange to me, that if I run the System Monitor, the CPU is running at 50% with out running any applications. What do I do/check to reduce that?

Also, is there a way to see which process is eating up the CPU?( Something similar to Task Manager in Windows, where you can see process by process the current CPU utilization)

Thanks a lot for any help.

Don't know about your AMD settings, but you can view the active processes running on your computer with their PID and memory usage with the "top" command. You have a lot of options with that one...

Perhaps this will help you understand the Linux method of memory utilization.

A good gui front end for the process lister, top, is gnome-system-monitor. KDE probably has one also (ktop?)

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

Use the

Code:

top

command. The output it will generate will tell you what application(s) are using up all your resources -- report back with the name of that program so we can help.
