I have not done a rigorous test (ie - me with a topwatch
rendering one scene with each version) but I think sometimes
I get a slowdown also ... not all the time though.

I think it's that pesky p4.  I have a p4 and they are slower
than an AMD chip running at the same clockspeed.  My guess is
that p4s have a sucky floating point implementation.

version 3.5 had some sort of routine for optimization on a
p4.  It used to display a line of text every time it
rendered that said something like "SSE2 detected - using
SSE2 optimizations".  I don't see this line of text when
rendering with 3.6.

I wonder this also.
