As a general note, I think it is quite hard to predict how any such
"optimization" is going to behave across even the common x86 family
processors. We've seen many times that optimizing for p4 is not the
same as optimizing for Athlon, etc. These days, benchmark results on a
single architecture are arguably no more valid than no benchmark
results at all.
That said, "my athlon is your athlon" (XP 2000+, will be running
-current after this weekend) for anyone who needs one for testing.
Not a speed daemon by todays standards, but it was yesterday...
