I used the very same dictionary - it was for testing!
The hardware might not be that relevant, I believe, as the other methods 
took times comparable to yours, while --prince was evidently much slower.
Anyway, I'm on a 4th generation i7 (Haswell) quadcore @ 1.8GHz with 8 GB 
ram. In prince mode, jtr tried 31317C/s. I was just surprised it took so 
much longer than in your case, having 2305 C/s. Maybe adding 1234 to 
your list (though it was there already) resulted in a sooner guess.

I could imagine that. I'll go through the installed docs. It's a bit 
early for me to write docs, but I'd be glad to help.

Alright, that explains it. I was just enabling OpenCL when I wrote, will 
give a try to the OpenCL-binary as well.

Thanks again!
