Has anybody done timings for gcc bootstrap / cross builds and

sensible modern configuration would be for gcc development, but the
the multimedia and games benchmarks I found on the web neither seem
particularily relevant, nor do they paint a uniform picture.
In fact the "gamer" benchmarks you are dissing are quite well
reflecting the very kind
of coding excessively found in GCC itself. Some observations suggest
the you should aim at the CPU with the biggest L2-cache size
affordable. In particular
comparision on the older Athlon XP line where very conclusive here as
there where similarly rated CPUs available with 256kB vers. 512kB
caches. Usually the 512k where 20% faster on GCC build loads then the
ones with smaller caches despite beeing significantly lower clocked.
