    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.
