Don't really know how that happened.
I can't reproduce it now.
With
$ ./john --list=build-info
Version: 1.7.9-jumbo-5+unstable
Build: linux-x86-sse2 OMP
Arch: 32-bit LE
$JOHN is ./
Rec file version: REC3
CHARSET_MIN: 32 (0x20)
CHARSET_MAX: 126 (0x7e)
CHARSET_LENGTH: 8
gcc version: 4.6.3
I get much smaller differences now (repeated several times, with similar
results):
$ ./john --test --format=nt
Benchmarking: NT MD4 [128/128 SSE2 + 32/32]... DONE
Raw: 5330K c/s real, 5277K c/s virtual
$ ./john --test --format=nt2
Benchmarking: NT MD4 [128/128 SSE2 intrinsics 12x]... DONE
Raw: 6746K c/s real, 6814K c/s virtual
And with
$ ./john --list=build-info
Version: 1.7.9-jumbo-5+unstable
Build: linux-x86-sse2i
Arch: 32-bit LE
$JOHN is ./
Rec file version: REC3
CHARSET_MIN: 32 (0x20)
CHARSET_MAX: 126 (0x7e)
CHARSET_LENGTH: 8
gcc version: 4.6.3
I get:
$ ./john --test --format=nt
Benchmarking: NT MD4 [128/128 SSE2 + 32/32]... DONE
Raw: 6877K c/s real, 6946K c/s virtual
$ ./john --test --format=nt2
Benchmarking: NT MD4 [128/128 SSE2 intrinsics 12x]... DONE
Raw: 6318K c/s real, 6318K c/s virtual
