Huh ?
Hartmut's computer has about 650 MB of free RAM (that's about the only 
useful figure in free's output : "real" free RAM + amout of RAM used for 
buffers and cache). I'd say that perfectly healthy. Caches and buffers 
don't count, as they are only used by Linux to speed up the computer, 
and the memory used by them is freed as needed for programs.

Furthermore, the 'free' program doesn't say anything about swap usage. 
For that, you'll have to run htop or gnome-system-monitor (and even 
then, it's only an estimation) or vmstat.

Bottom line : 90 % of RAM usage is normal :

And I have no swap, as it is useless with 6 GB of RAM.
