This looks pretty decent for a system running X. Are you running KDE (as it is Kubuntu)? Consider a lighter Window manager? > This is what usually what gets recommended in forums and such.

It looked to me like you were poking at the system at random, removing or optimizing stuff you knew would not make a difference.

Let's be wildly, irrationally, exuberantly optimistic and assume you will gain 10-20% (highly unlikely) - that won't help you, really, will it? "Removing unnecessary features" sounds more drastic to me than just recompiling. Most programs coming with major distros are already stripped. I checked my FC4 and Xorg seems not to be stripped. You may try checking (file(1)) and stripping (strip(1)) that, I don't know if it may cause any problems.

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." ;-) -- Oleg Goldshmidt | [EMAIL PROTECTED] | http://www.goldshmidt.org ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
