In several platforms using the driver acceleration for a hash is actually slower (but nevertheless it offloads the burden from the main cpu). If you didn't then the handshake time shouldn't be affected by cryptodev at all. During handshake RSA and DH are used which are not accelerated by cryptodev. cryptodev comes into play during data transmission and that is where you are going to see any acceleration. regards, Nikos
