Memory Consumption

[Julien Tane]

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
