after discussions with Marcelo Kaihara (thanks to him) I was able to reproduce
his results with openssl-1.0.0c on a 2-proc 3Ghz AMD Phenom(tm) II X2 B55:
I configured OpenSSL with GMP as follows:
$ ./Configure linux-generic64 enable-gmp -lgmp -L$GMP/lib -I$GMP/include
Should I interpret the command line as if this is for GMP 5.0? What GMP
configured for the host processor of this system? If it is, OpenSSL is
poorer than I had expected...
My point still holds: the numbers of the slides do not currectly show
the performance of GMP on RSA-2048. At best, the numbers are a good
comparison between OpenSSL's max performance on RSA-2048 on a 1.5 year
old midrange CPU, with raw code running on the very latest highend GPU.
The main GMP development system. a 3.2 GHz X6 system, gives over 6400
RSA-2048 decrypt operations per second. That's without adding the
