Maybe it's the codec?

Subject: [PD] GEM: abnormal performance difference PC/Mac?
I'm working on a patch that has 16 [pix_film]s each one playing back a
short loop of video; videos are approx 400x700 size, encoded with
Animation and have an alpha channel.
On a PC with a 2.5GHz dual core (T9300) and Windows, it _almost_ works
smoothly: with 10-12 videos it is just fine.
On a MacBook Pro which has a 2.4GHz dual core it is _much_ slower. Even
with only 4 or 5 videos playing, it goes at less than half of the
Can the hardware really explain that much difference in performance? Is
an intel T9300 that much more powerful than the processor of a MacBook
pro? (certainly not because of the 0.1GHz more)? Or the GPU (Nvidia
GeForce 9500M GS)?
Or is there some "software" reason for such a huge performance penalty
on Mac OS??
