Redhat 8.0 Incredibly slow with Pentium III Processor
Red hat's working fine but incredibly slowly, it can take up to a minute to switch between workspaces, I think I need a new processor. Am I right? and if so can anyone recommend a cheap but better processor than the one I have got already, cheers

I doubt it would be your processor being too slow.

A Pentium 3 CPU should be more than sufficient for most desktop uses.
It sounds rather like there is some other issue.

What services do you run ?
Could you show what you get when you type in


in a console ?

Ram, get some ram....

I've had a chat with a Mac freak, he suggested RAM as well.

Get more RAM and switch to a lighter desktop environment (or WM) than KDE or Gnome. I am a big fan of both XFCE4 and Fluxbox, both of which perform well on my 366MHz P2 laptop with 192MB RAM.

Also, as suggested, disable all services that you don't really need for gains in performance and security. I often see people running database servers (often more than one!), web servers and a host of other things although they never once have used them.


andrewgates1979 08-17-2004 10:07 AM

more ram works great, cheers

hw-tph 08-17-2004 12:45 PM

It took a while until you got around to answering, eh? ;)
Glad it works better now!
