title: Tools to test SSL performance
body: <p>I'm trying to implement a TLS server with a custom engine (my server has a hardware accelerator).
  I want to test the performance of my server w/ wo the engine such as number of handshake per second, number of connection...
  I found a lot of online website to test SSL server but couldn't find anything to do that locally (since I can't bring the server online yet).
  Is there any tools/ software to achieve this?</p>
