Why is Qtopia much faster?

[Yorick Moko]

This might be a stupid question, but it isn't the first and will not
be the last stupid one I ask :).
I have glimpsed at the 2007.2, ASU and qtopia image (the latest
builds) and a very noticable difference is the speed.
Will this improve in the ASU and the 2007.2 or should I not get my
hopes on? Qtopia just responds and seems to load everything faster.

Kind regards,
Yorick
