Is there hope to have KDE 4.x lighten up?

Aside from the expected bugs/instabilities, I have found KDE 4 to be
quite "heavy".

I had to go from a Celeron 2.4GHz + 1GB of DDR333 to a P4 3.0GHz +
3.5GB of DDR400 to get to a comfortable KDE 4 performance. I'm seeing
a lot of machines coming out with Atom processors, and I'm wondering
how well is KDE 4 going to feel on those. I had read that Qt4 was
supposed to make KDE4 quicker than KDE3, so I'm wondering if the
current lack of speed are just due to left over stuff from KDE3 or
otherwise.
