Perhaps an email to gcc-help would get the info that you need. I could be the go-between but I don't feel like I know enough to convey your questions. Perry Smith Ease Software, Inc.

Could someone who is using the Intel compiler say something about the performance of resulting binaries compared to binaries created by GCC. I'm obviously mostly interested in the speed of the python interpreter.

for C++ code which is doing recursive / parallelisable tasks with processor optimisation flag -xP (for an intel core duo chip) it is faster than gcc4 with optimisation for auto vectorisation and other speed optimisations
At least in my case. Of course mileage might vary... I suggest its at least worth running some benchmarks so wee what differece it makes for various kinds of tasks in python.
I was hoping that someone had already done that :-). Having a look at the intel compiler is somewhere on my todo list, ever since a college noticed that he got higher pystones in Windows running in Parallels than running natively on the same mac.
