Konsole get's sluggish after hours..

Actually I have been noticing the sluggishness of linux after a while, since 
Suse 5.3 (my first foray into this tangled web (no pun intended)).  On a 
computer with the same memory and hard drive size (actually the same computer 
with a removable drive), net access is much slower.  I have mentioned this in 
the past, with no response.  Must be a retorical problem!  This is 
unfortunate because I am one of those who does not like what Mr. Gates has 
done to the computer industry, and likes the basic premises of linux, mainly 
no hidden agenda to make another buck.
