Sudden and Unusual slowness, esp. Firefox, on my Centos5.7 desktop using KDE desktop


For the last week my Centos5.7 desktop (which I update daily) is processing very slowly with lots of freezes, although it does do "catchups" every four minutes or so. In Firefox it is half the speed it was a few weeks ago and the flash games which I enjoy on Facebook are and agony with slowness and crashes,some will not load at all. The operating system is not comfortable for me I spent years using windows but this bears no resemblance. I am especially new to "compiling". Until this installation of the tablet I got by nicely just adding in needed program files using Yum or rpm packages. What can I do to speed my system up and smooth out the processing? How can I find if it is the network configuration or memory management which is the problem?

I'd appreciate any insights you might have, bearing in mind I am a novice in this system.

there's a good chance your system is swapping (i.e. using disk to extend ram capacity at the expense of speed).

to check this possibility, as well as as other options, please post the output of the following command:

seems to have lost the formatting: does this help? I am using Konqueror to post this, Firefox just freezes constantly and I am out o extension to turn off. Is there a way to adjust the swap file?

Since this post I've upgraded to Centos 6.2 and added in a gig and a half more memory and it is no longer slow.
