"used" as in not buffered or cached. I'm sorry if I wasn't clear.
This looks pretty decent for a system running X. Are you running KDE
(as it is Kubuntu)? Consider a lighter Window manager?
I don't know. I use KDE and qt programs (LyX, kolourpaint, ksnapshot,
etc) as part of my regular workcycle so the libraries and some KDE
subsystems will be in memory anyway.
The largest process I could find is Xorg, which (according to pmap)
consumes about 150M, very little of it is libc and libdl.
Libc and friends are never a problem.
That was mentioned just to show that I'm not counting all of pmap's
output against X, I know libc isn't a problem.
The problem only starts when I run Matlab (and I expect to run some
heavy tasks with it in the near future).
Ah, that's heavy beast. I have not used it in the last several years,
but it is easy to check the system requirements on
http://www.mathworks.com/support/sysreq/current_release/unix.html
- 512M RAM, 1024M recommended. Sorry, but it sounds like "swap
is for MatLab users." ;-)
Interesting, that's twice what the book I got with Matlab says, I guess
they forgot to update the book. It does sound like "swap is for Matlab
users" :-) At least I can optimise that by using Octave for heavy stuff
that does not require abuse of the visualisation features of Matlab or
toolboxes that rely on Matlab language features unavailable in Octave.
