No, binary execution in gcc3 is *much* faster (really there's no
reason to use gcc2 any more, i.m.o). On my code (computational
biology stuff) gcc3 is almost as fast as icc 8, sometimes faster.
For the end user, that's what matters. Plus there's the
improvements and standards-compliance in C++, etc.

2 deserves to die and is unsupported upstream. Eventually, 3 will
also die upstream.
GCC 4's release notes are here:
It has a new optimisation framework, Fortran 95, and other things.
Eventually they expect compile times also to improve.
