Acer's Linpus Linux Lite (Fedora) ultra portable laptop piles the pressure on Microsoft (FSM)

It's probably with the worst possible options of GCC, as I found it in the mouth of some of my
(non-free software loving) colleagues and on the Intel site ;)

More seriously, I can believe that ICC will have optimizations before GCC for this processor,
and would bet you can get this kind of improvement figures with some particular uses
(multimedia ?).

Not sure there'll be much difference on a web/file server though, as memory and disk access
will make the bulk of the response time.
