PLEASE NOTE, I was using the 3 column effect so ALL the messages were being listed from top to bottom in the application whereas most people only show 4-10. When I switched back to "Classic view" only showing a few emails, it scrolled a lot faster, but this is not what I want.

Not sure what you're describing -- on my system "classic view" has
about 15 messages listed in the top-right panel. I tried switching to
"vertical view" with no change in scrolling speed. (Of course maybe at
some point I dragged the panel to expand the message list -- if I want
to actually read a message I open it in a new window).

If you have scrolling issues on other applications it could be an X
driver issue (the "jaggedy" scroll area might indicate that too).

OH and I'm running Ubuntu 8.10 Intrepid. Are you by chance running a
pre-release version of 9.04 Jaunty?

If Mutt works better for you, then that's all the better. You can
ditch X entirely and save the heartache and startup time whenever you
log in.
