Software Crypto Performance
Interesting results - Solaris 10 08/07 (update 4) on v440, no crypto card.
openssl speed rsa1024 -engine pkcs11 -multi N
openssl speed rsa1024 -multi N
Where N was 1 2 4 8
As you can see even without having crypto card there's huge performance increase by using pkcs11 - different algorithm implementation and different compiler?
