Yes, but my question was about speeds of john-omp.exe - I don't think
you provided any numbers for that (except for CPU time use percentages).

OK. There was in fact a known slight performance regression with NT in
1.7.9-jumbo-5; it's been addressed in magnum's tree, so the next jumbo
should have faster NT (should be about the same as NT2 then).
And perhaps you can contribute some optimizations, too. ;-)
