Well, maybe. I don’t' remember if he gave us a 'top' output, which includes the 'load avg'. If that is much above one you're probably disk limited. I'd be very interested in the top part of the 'top' output.
And I've been using 'underpowered' CPUs for a long time and not feeling much if any pain - but then I tend to overkill the ram. 4G is minimum, IMHO.
Also 'just browsing the web' CAN eat lots of memory.... Which can drive you into disk thrashing. Been there, done that WAY too often...

Subject: RE: memory
My question is what is the computer used for? Are you using it for your Linux from scratch project?
If your just browsing the web and doing email, I wonder if more RAM will really make a difference.
When you posted your memory usage I think you had more than 400MB free.
I did a search and it appears you are running the AMD Athlon 64 3500+
(2.2 GHz) processor which by today's standards is not a very powerful CPU. That might be why things are slower than you might like.
