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.
