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