Lucio,
Thanks for the reply.
I agree however with Liam: terminals don't use a lot of memory.
Liam: I use 64-bit (the Phenom II is 64 bit 4-core) and I also haven't
tweaked the "swapiness". I think that with 4 GB and the modest load
swapping shouldn't be necessary. Moreover the fact when the system is a
little bit heavier loaded, it takes sometimes more than 20 seconds for
simple things like starting a program and the disk light is continuously
on, moreover, delays increase when the time between restarts increases.
CLifford: the culprits may well be firefox and thunderbird, which I both
use continuously. In firefox I have ~ 25 windows open some with flash
(at least flash is installed).
Rashkae: no I don't think that VMware reserves so much swap-space as at
the moment is in use, although some vmware related processes are still
running.
