RAM upgrade.

[David Mangani]

Thanks for all the different viewpoints. When first set up and installed ( RH9 
) my system was configured with 128MB of physical memory. The swap set up 
during install was 256MB ( the ole 2*ram rule ) . I have checked several 
times over the last few days and the swap space has rarely gone over about 
40% usage, and that was with KDE, Netscape, Kmail and Gaim running at once. I 
suppose that for now, I may just leave it be and see how the system behaves. 
I hate to mess around a whole lot as I have my system running nicely right 
now. I thought perhaps there was some simple way to "adjust" the swap space 
without repartitioning etc. Once again thx for all the input.

Dave
