Hello.
I got a small problem when it comes to memory usage (excluding the apps that I usually use, such as Firefox, Gaim, Azureus). I got (excuse the expression) shitloads of system processes running at once.
Here you see a list of most of them: http://img133.imageshack.us/img133/1...enhot138no.png
Now, I know I need tor, udevd, cupsd, reiserfs/0, dhclient3 and cron, but which ones do I not need from that list? I wanna cut down on memory usage.
Thanks.

Well, I can't scroll down a png :-)
But more to the pt, it all depends what you want your box to do ie what do you use it for.
The best way is to google each process and decide if you need it. Be careful though, becuase some (sub-) processes will be used by processes you want.
You can try killing them if it looks like you don't need them and see if anything else breaks.
Note that Linux always caches everything it can, so the 'top' cmd usually shows it using practically all your RAM and a small portion of swap. This is perfectly normal....
IOW, you may well not have a problem.
Is the machine struggling in any app?

The system processes are shown in that pic, but not the user processes (like KDE and such).
I did try googling, I always reach some useless mailing list, that's why I asked here.
I kinda don't feel like killing then seeing what happens.. lol
