Memory Hog kde or just Suse?


Ok I'm sure someone else is experiencing this problem too and has already posted since Suse 11.0 beta 1 is due out in a bit. BUT.... in a laptop with 4GB of RAM intel 2.0GHz duo running Suse 10.3 x86_64 running so slow?

'free -k' shows that of my 4Gb of RAM I have 3.9Gb taken up and only 84kb of my 8Gb swap space being used. Checking vmstat I see that this is cached memory. But why when I click the kstart bar thingy does it take ages to load?
If I check top I see that Xorg is taking up an astounding 880Mb of RAM.
When I'm running a command line based program language and kate text editor (I'm not fully integrated with vim I can't even switch desktops !!! What is going on here

You can always kill the desktop and see what that does to your memory footprint. Stop kdm (or gdm or xdm) and it should kill X and KDE. Then you can see if it's just Suse.

I've never used SUSE, but I use KDE all the time. None of my computers have more than 1gig of RAM; most of them have 256megs, and run KDE just fine. When I say 256megs of RAM I mean a TOTAL of 256megs of RAM with NO swap and /tmp mapped to a tmpfs ramdisk--these are diskless net-booting PCs. If I open up a web page with a huge 4000x6000 hires scanned image, then the Iceweasel web browser will unceremoniously crash, but KDE itself runs just fine.

I suppose SUSE is bloatier than Debian Etch, but even so 4gigs of RAM really should be plenty. I'd guess there's something else weird going on, or maybe SUSE 10.3 just has some horrible flaws.

How about you post the twenty top lines from top's output
after having sorted by size?

And the same sorting by CPU?


Cheers,

So it doesn't always do it. But a lot of the time I get a slow responce from the GUI on applications. Such as firefox took forever 2.5 minutes to be fairly precise to get to the post it page here. I'm sure it isn't my connection with the university's high speed connection. Anyway I'm starting to look at changing over to Debian after a project is over.

Cheers,

I've posted the output from top below
