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):
