description:
Add support for building the assembly versions of some BIGNUM
routines from OpenSSL. Speeds up DSA significantly. A similar
gain should also be seen for RSA.
Before:
Doing 512 bit sign dsa's for 10s: 965 512 bit DSA signs in 9.97s
Doing 512 bit verify dsa's for 10s: 766 512 bit DSA verify in 9.93s
Doing 1024 bit sign dsa's for 10s: 276 1024 bit DSA signs in 9.99s
Doing 1024 bit verify dsa's for 10s: 217 1024 bit DSA verify in 9.93s
sign verify sign/s verify/s
dsa 512 bits 0.0103s 0.0130s 96.8 77.1
dsa 1024 bits 0.0362s 0.0458s 27.6 21.9
After:
Doing 512 bit sign dsa's for 10s: 3742 512 bit DSA signs in 9.88s
Doing 512 bit verify dsa's for 10s: 3065 512 bit DSA verify in 9.92s
Doing 1024 bit sign dsa's for 10s: 1357 1024 bit DSA signs in 9.99s
Doing 1024 bit verify dsa's for 10s: 1094 1024 bit DSA verify in 9.83s
sign verify sign/s verify/s
dsa 512 bits 0.0026s 0.0032s 378.7 309.0
dsa 1024 bits 0.0074s 0.0090s 135.8 111.3
