Subject: statistics -openssl vs john

Hi, I was doing speed test between openssl des and john des. I get
following statistics for openssl

type             16 bytes     64 bytes    256 bytes   1024 bytes   8192
bytes
des cbc         100225.76k    89521.76k    89778.20k    95060.70k
96158.84k

and for john

Benchmarking: Traditional DES [32/32 BS]... DONE
Many salts:    434566 c/s real, 997527 c/s virtual
Only one salt:    426208 c/s real, 568277 c/s virtual

Benchmarking: LM DES [32/32 BS]... DONE
Raw:    9306K c/s real, 12086K c/s virtual

Now considering openssl, it can process 100225.76 x 1000 = 100225760
bytes/sec which should account to 100225760 /8 = 12528220 encryptions/sec
(since DES block size is 8 bytes)

With john, considering LM DES (which according to what I read does 2 DES
encryption), the result is  9306 x 1000 = 9306000 x 2 = 18612000
encryption/sec

This provided 1.48 times speedup with john des (non sse or other
optimizations). Am I right in my calculation?
