upgrade to 10.2 -> system getting slower


I have upgraded to 10.2 yesterday, keeping my old kernel 2.6.11.12. The only major change I've done is using freetype-2.1.10-i486-1arf.tgz from linuxpackages.net, in order to use a byte-code interpreter enabled version of freetype.

I have noticed that KDE starts up slower, but I am more concerned by heavy CPU usage by both firefox and X. Simply scrolling a web page in Firefox makes the CPU usage go up to 25%-35%, and opening a new web page in Firefox uses like 50% CPU for Firefox itself.

On Slackware 10.1 I also used Firefox (from linuxpackages, again) and my impression is that it responded much quicker.

Does anybody else have this impression?

can you post the output of ps -aux both immediately after boot in runlevel3 and then after loading KDE?

I don't know how much it'll help, but you might try disabling arts as it's using a considerable chunk. KDE itself uses several 1-2% chunks. I just checked my own and X uses 2.5%. When I opened Firefox, without an internet connection and without loading any pages or files, it uses almost 12%.

What kind of hardware do you have? It might help to use a less resource-hungry window manager. KDE is the bulkiest with the most overhead.
