On my machine (AMD X3 720), I am getting normal speeds:
$ ../run/john -format=ssh -t
Benchmarking: ssh [32/64]... DONE
Raw: 122777 c/s real, 122777 c/s virtual
However on bull development machine, I too am getting very high speeds:
$ ../run/john -format=ssh -t
Benchmarking: ssh [32/64]... DONE
Raw: 811164 c/s real, 811164 c/s virtual <=== awesome speed :-)
Also, the code on bull works correctly. I manually verified by
cracking my ssh key collection. The code is same between my and bull
machine. Nothing has changed. Very strange.
One more observation, during actual cracking the speed is quite low
compared to benchmarks,
$ ../run/john -i sample
Loaded 1 password hash (ssh [32/64])

Any ideas what is going on?
