12 # MD5 for SPARCv9, 6.9 cycles per byte on UltraSPARC, >40% faster than
13 # code generated by Sun C 5.2.
15 # SPARC T4 MD5 hardware achieves 3.20 cycles per byte, which is 2.1x
16 # faster than software. Multi-process benchmark saturates at 12x
17 # single-process result on 8-core processor, or ~11GBps per 2.85GHz
