Hmm.. hadn't noticed there is an openmp version for w32... So... Fresh batch of benchmarks for both 1.79 and 1.79j5 (Windows XP 32bit, idle desktop, no apps running, trimmed-down services).
179 DES 3727K (many) / 3576K (one)
179j5 DES 3748K (many) / 3536K (one)
179OMP DES 5618K/2863K (many) / 4804K/2500K (one)
179j5OMP DES 5652K/2891K (many) / 4853K/2524K (one)
--------
179 MD5: 11051
179j5 MD5: 34403 (SSE)
179OMP MD5: 21667/10882
179j5OMP MD5: 66860/34213 (SSE)
---------
179 Blowfish: 1005
179j5 Blowfish: 997
179OMP Blowfish: 1983/992
179j5OMP Blowfish: 1991/996
---------
179 Lanman: 49542
179j5 Lanman: 49812
179OMP Lanman: 47304/35628 (negative performance gain)
179j5OMP Lanman: 46950/36083 (negative performance gain)
If you want some of these added to the wiki, I'll post them there too - no problem.
