If they really wanted to test the speed why didn't they use more aggressive compiler flags?
I think it should be investigated which packages could be compiled by icc since
intel are now providing it for free for non-commercial use. I did some tests with it and
whetstone (classic fpu benchmark from the 1970's) doubled in speed compared to gcc on a P4, and
it was about 75% faster on an Athlon-XP. Now float-point isn't everything but from my experience
icc generally produces better optimized code than gcc unless the application has been hand-tuned
(like mplayer).
I tried installing gentoo with CC=icc once but I had problems with many ebuilds so I dropped
that idea. At the moment extremely few ebuilds support icc.
