This speedup the performance (not in the benchmark, in the "real" c/s),particularly in the incremental mode with near a 30%. - Add SSE2 code with a speedup of 20% over C code. Note that "plain" SSE2 code are a little bit bad that C code because the emulation of the rotate instruction that dont exist in SSE2 (gcc are smart enough to produce rotate instruction in the C code). The speedup is because i intermix SSE2 code with x86 code trying 5 passwords in parallel. I am now working in the x86-64 code. -- alain View attachment "john-1.7.2-ntlm-alainesp-5.diff.txt" of type "text/plain" (24786 bytes) -- To unsubscribe, e-mail john-users-unsubscribe@...ts.openwall.com and reply to the automated confirmation request that will be sent to you.
