Your problem is most likely Flash/Javascript based (I'm basing my
theory on the fact that there's a lot of Ajax related stuff on the site).
No matter what OS you have, if a website's slow (and it's not
because you don't have OpenGL support in your X-server), slowness will
remain constant. It's just the way unfortunately that browsers are designed.
NoScript combined with Adblock will help quite a bit though for
whitelisting domains and javascript/flash content.
