Thanks for your feedback Len.
You explained how the glibc optimisations work in a manner making it

Much appreciated!

Just ask yourself: How many months per year does your cpu execute code
from glibc instead of kernel or app code? If you ca
Hi Brock,
I have tried lmbench and recompiled glibc 2.21-6 with -O3 and -O2
optimizations with the cflags below:
extra_cflags = -mcpu=G5 -mtune=G5 -maltivec -mabi=altivec
I haven't actually seen any marked difference to the results coming out
of lmbench when using the default Debian glibc and
