Hello!
JFYI:
I compiled python using each of gcc and icc.
(on compiling with icc, I compiled 6 sources with gcc by hand
to avoid icc's error hehe.)
Their binaries have visible speed differences.
This is a benchmark/pybench result.
PYBENCH 1.0

Machine Details:
Platform ID: FreeBSD-4.5-STABLE-i386-32bit-ELF
Python: 2.2.
icc Compiler: C
gcc Compiler: GCC 2.95.3 20010315 (release) [FreeBS
icc Build: Apr 19 2002 06:59:32 (#1
gcc Build: Jan 21 2002 20:19:08 (#1

Tests: per run per oper. overhead
