I have what sounds like a similar problem on my Mac (Mathematica
6.0.0, Mac OS 10.5.2).  After I launch Mathematica, the first
expression I evaluate can take a long time (comparatively- I don't
think it's ever been longer than one minute).  I've found that if I
manually launch the kernel before evaluating any expressions, this
delay is eliminated.  For some reason, letting the kernel launch
automatically with the first expression I evaluate takes much longer
than launching the kernel manually, and then evaluating the first
expression.  I have no idea why this is.  If you find that manually
launching the kernel solves your problem, there is a way to set up the
kernel to launch automatically whenever you start Mathematica- look in
Evaluation>Kernel Configuration Options...  Sorry I can't give a
better explanation!
