Thank you for the useful information. Are you aware of any attempt of adding an openssl speed test for tls/dtls record layer protection? I'm thinking of a method of measuring how many tls/dtls record layer encapsulation/decapsulation operations openssl can perform in a given time. I don't need a communication channel, I only want to test the performance of the authenc operations in tls/dtls context. Thanks, ta
