Even if you end up building NSS with optimizations, they use the regular multiply instructions, which performs best on AMD chips, but not as well on Intel CPUs. For Intel, one needs to use the SSE2 and above instructions set, which NSS currently doesn't do - except on one platform, Linux.

Is there any reason why we can't use the same optimizations on Darwin/x86
as we use on Linux?
If darwin/x86 uses gas, then it's should be just a matter of setting some defines in the freebl make file and testing. (the primary thing that holds back using these assembler optimizations is differences in the assembler syntax on our various platforms).
