Well it's not very efficient, but it works: Benchmarking: NTLMv1 C/R MD4 DES (ESS MD5) [128/128 SSE2 intrinsics 12x]... (4xOMP) DONE Many salts: 13141M c/s real, 8111M c/s virtual Only one salt: 53581K c/s real, 32671K c/s virtual This is on 2.3 GHz i7. BLOCK_LOOPS is 1536. Using the HT crap (8xOMP) just slows it down. Almost 1000x the J7 speed with 8xOMP at 13484K c/s. The HT does a little good in that version. BTW, the same BLOCK_LOOPS for NT2 give a fair boost too (same "slow" laptop): Benchmarking: NT MD4 [128/128 SSE2 intrinsics 12x]... (4xOMP) DONE Raw: 66373K c/s real, 36670K c/s virtual magnum
