Here is what I see in a 32 bit intrinsic build (cygwin). Now, this is not
jumbo-5, but I did not think anything changed about how md5_gen is built,
since then.
$ ../run/john -test -form=md5-gen
Benchmarking: md5_gen(0): md5($p) (raw-md5) [SSE2 16x4x2 (intr)]... DONE
Raw: 9653K c/s
Benchmarking: md5_gen(1): md5($p.$s) (joomla) [SSE2 16x4x2 (intr)]...

Many salts: 8321K c/s
Only one salt: 5404K c/s

Benchmarking: md5_gen(4): md5($s.$p) (OSC) [SSE2 16x4x2 (intr)]...
Wait...

I will later check this on my pen drive linux-64 system, to see if there are
problems showing up there, which do not appear on this 32 bit build.
Jim.
