PIII/664 - OpenBSD 3 .0 + Comment
As the original poster noted, these benchmarks shouldn't be taken too seriously. For instance, upon perusal of the OpenSSL 0.9.6b sources, I see that several modules are written in assembler for the x86 platform. Whereas no such hand-coded optimizations exists (yet) for PPC, and it appears that the precompiled version included with OSX wasn't built with any SIMD/Altivec-specific support besides the usual -O3 switch.
