Hello Fred,
thanks a lot. I had been wondering in the last days. I mean this is O.K now... But Can it be that some useless things are cached or buffered.
Is there a way to find out what is buffered or cached ( or perhaps tell which application buffer and cache so much ?).
Regards,
Julien

Hello,
Can anyone tell me what in my computer takes so much RAM?

You asked:
So where are the 200M missing memory ?
Can you give me a hint?
Yes, look at the "cached" and "buffers" lines in your posting above. Those two total to around 235-240 megabytes.
This is NORMAL. Linux does this ON PURPOSE. you've got all that RAM sitting
there that would otherwise be DOING NOTHING, so the kernel puts it to use
providing perfomance-enhancing buffering and caching. These things can be
quickly freed if necessary, in case some program suddenly demands additional
RAM, so it's not like it's a problem.
