I try LM, MSCASH and NTLM. I do not know NTLM do not have OpenMP support.

Will do and i report back.

I take a look at this numbers. One difference its that i use a laptop
CPU, other its that i perform a "real" benchmark and not the "-test"
option. I consistently found differences in "-test" option and "real"
crack speed. I will test the "-test" option and review the method i
use to gather performance data.
