Hi all,
sbc-bench is now on Github: https://github.com/ThomasKaiser/sbc-bench
I'll link from the README there to this thread for further discussion about the tool and proper benchmark methodology.
did you ever tried cryptodev for the R2. I think you had to compile openssl as well (as far as I now, there're some issues with openssls cryptodev implementation, but honestly never cared). Just out of curiosity.. I only gave it one shot back then cause the board had bigger issues than crypto in those days.
