Hi to all. This is my firs post in english (I’m not the best writing in english).
I made a Benchmark for LM Cracking using my laptop:
Dell XPS M1530
Intel Core 2 Duo T7500 2.2Ghz
4 GB RAM
Windows Vista Ultimate
Hard Disk 120 GB 7200 RPM
Nvidia Gforce 8600M GT 256 MB
I Used:
- John The Ripper (386 and mmx)
- Cain
- Elcomsoft Distributed Password Recovery
BENCHMAR
The objetive was test how many password/seg could be cracked using diferent software.
There are crackers based in cpu and recently in gpu.
For CPU test, I used John the ripper (386 and mmx) and CAIN.
For GPU test, I used Elcomsoft Distributed Password Recovery. Although this software allow more than 1 cliente, I only used my own laptop.
Here we go.
JOHN THE RIPPER 386. Speed: 4 M/s

John the ripper 386 test in core 2 duo 2.2GHZ
JOHN THE RIPPER MMX. Speed: 9.2 M/s

John the ripper mmx test in core 2 duo 2.2 Ghz
CAIN. Speed: ~8 M/s

Cain cracking LM hash in core 2 duo 2.2 Ghz
ELCOMSOFT DISTRIBUTED PASSWORD RECOVERY (GPU). Speed: 22.5 M/s

Elcomsoft Distributed Password Recover with 1 GPU cracking at 22.5 M/s
FULL RESULTS
EDPR (gpu): 22572914 c/s
John mmx (cpu): 9230000 c/s
Cain (cpu): 7969348 c/s
John 386 (cpu): 4043000 c/s
