Well, that's true if you spend most of your time waiting for the compiler to
run, but when it takes longer to compile AND runs slower
(http://www.cs.utk.edu/~rwhaley/ATLAS/gcc30.html) you lose on both counts!

Anyone have good benchmarks to run to compare raw kernel performance to see
how much using RedHat's recent (2.96) or 3.0 compilers to compile the kernel
perform vs the older compilers?
