...to measure, but it was definitely real slow with the gcc compiled version. Okay, what's going on inside the OpenSSL code.... there are two small functions which are responsible for about 95% of the CPU clock cycles. These are bn_mul_add_words() in the file crypto/bn/bn_asm.c and the function BN_mod_word() in the file crypto/bn/bn_word.c. The first is responsible for the miserable RSA speeds, and the later for the horrible DH speeds. I'll discuss how to speed each of these up separately. The bn_mul_add_words() function is by default implemented in the file bn_asm.c. However, neither the gcc...
