I didn't list FreeBSD MD5 as a regression, but dynamic_27: FreeBSD MD5 $ grep -A 1 "FreeBSD MD5" j5-sse2.txt Benchmarking: FreeBSD MD5 [32/32]... DONE Raw: 4283 c/s real, 4283 c/s virtual -- Benchmarking: dynamic_27: FreeBSD MD5 [SSE2 4x1]... DONE Raw: 6172 c/s real, 6234 c/s virtual $ grep -A 1 "FreeBSD MD5" j6-sse2.txt Benchmarking: FreeBSD MD5 [128/128 SSE2 intrinsics 12x]... DONE Raw: 6540 c/s real, 6540 c/s virtual -- Benchmarking: dynamic_27: FreeBSD MD5 [SSE2 intrinsics 4x3]... DONE Raw: 5607 c/s real, 5664 c/s virtual So, in jumbo-5, the dynamic_27 format was faster than the native --format=md5. But that's not that relevant, because in current git, the native --format=md5 outperforms --format=dynamic_27. Frank
