I suspect it's the semantic desktop thingy that's at fault (I guess it's database and indexing service must eat tons of RAM), since I have it disabled and this is how it looks here after 5 days uptime: total used free sharedbuffers cached Mem: 5973 3534 2438 0 1056 1685 -/+ buffers/cache:793 5179 Swap: 917 0917 (The important value is -/+ buffers/cache: 793) This is with KDE 4.5.1 and semantic-desktop USE flag disabled.

This install is a few years old and my rig is several years old. It's been doing fine so far. I'm also using the same KDE. Currently running, KDE, Seamonkey and a nice emerge of a video package. The compile process is using the most memory at the moment. Dale :-) :-)

Why? It reports 896MB usage vs 3271MB in Florian's system. Looks pretty normal to me.

Why? It reports 896MB usage vs 3271MB in Florian's system. Looks pretty normal to me. I THINK I read he was up for about 8 days. I had just booted up a little bit ago. Looking at the Mem line, I am using almost all of my memory already. I was also keeping in mind that the OP has about double the memory that I have. I'm just not sure what exactly is wrong with his either. It was more of a question than anything. He is using a lot of swap but that can be adjusted by setting the swappiness file with a lower value IF he wants to do that. I have mine set to 20 or so. I prefer to keep as much in memory as possible but at the same time, I don't want to crash if say GIMP gets a little memory hungry when I open 300 images all at once. I did that once. It took a while. lol I was always told that Linux uses memory a lot better than most other OS's especially M$. Cache as much as possible and run faster which means it will use all the memory at some point. Mine does that way and always has. Since the kernel handles all this, I'm not sure what the OP can do to fix anything unless it is a kernel bug. Then a upgrade may be the sure. I guess? Dale :-) :-)
