when you did that command your system was running slow?t
how slow is it? i mean you have 'only' 128 MB of RAM, how fast you want it to be?
RH 9 is new (and big) os, maybe you should go for some some of the smaller ones...or install less programs (maybe even without KDE and/or gnome, but using iceWM or similar)
it seems that you have enough swap (i have ~500, and using rarely more than 0...)
