Help webpages is lagging when navigating on the galaxy s


I can't understand how this phone, can be so laggy on simple internet pages (fx this site).
When i scroll left/right/up/down is is very laggy (u can compare it to low frame rate).
My old iphone 3gs, is much more smooth when navigating web pages.

I'm aware that there is a problem, causing the galaxy s to be very laggy (mine is too), when starting, switching ect apps.
But when the browser is loaded, and the webpage is loaded, I would assume that it would have the power (at least more power than 3gs) to navigate smoothly, but again the phone disappoints me...

Any thoughts?
