I also tested it on Quad Corei7 (2.8 Ghz).  Note the difference in performance with OpenMP vs. Standard.  These were compiled using gcc 4.6.1.

Standard (no OpenMP):
../run/john -test -format:DES
Benchmarking: Traditional DES [128/128 BS SSE2-16]... DONE
Many salts:	4985K c/s real, 4985K c/s virtual
Only one salt:	4780K c/s real, 4780K c/s virtual

../run/john -test -format:LM 
Benchmarking: LM DES [128/128 BS SSE2-16]... DONE
Raw:	66462K c/s real, 66462K c/s virtual


OpenMP (default is 8 threads):
../run/john -test -format:DES
Benchmarking: Traditional DES [128/128 BS SSE2-16]... DONE
Many salts:	13284K c/s real, 2128K c/s virtual
Only one salt:	11862K c/s real, 2011K c/s virtual

OMP_NUM_THREADS=1 ../run/john -test -format:DES
