Intel(R) Core(TM) i5 CPU       M 540  @ 2.53GHz

That is a two core cpu with hyperthreading of 4.

It takes about a second. If I time it manually I get about 1.4 to 1.5
seconds, by looking at the status bar. I can even make it three to
five seconds. Same board, just zoomed in. It is not a complex board,
it just contains a few footprints, a three VRML models and a STEP
model.

That feels way better.

I think that will be a sane solution. I don't mind too much, I just
noticed the behaivour.

I think it needs to be a frame of gold leafs. :P
