But IIRC I saw similar delay at that point even with mmap. Most of this weird delay (4 seconds maybe) is between these two lines: Loaded 29012258 password hashes with no different salts (Raw-MD5 [MD5 128/128 SSE4.1 4x3]) and: Node numbers 1-8 of 8 (fork) whereas the delay between the "Node" line above and: Each node loaded the whole wordfile to memory is maybe only 1 second or less (the wordlist file is likely already cached in RAM from previous invocations). BTW, got even better time on a second invocation: real 1m1.727s user 4m48.066s sys 0m22.143s Still same 2x E5420 machine. Alexander
