> Test new Producer and new Consumer performance with and without SSL/TLS once the SSL/TLS branch is integrated.
> The ideal scenario is that SSL/TLS would not have an impact if disabled. When enabled, there will be some overhead (encryption and the inability to use `SendFile`) and it will be good to quantify it. The encryption overhead is reduced if recent JDKs are used with CPUs that support AES-specific instructions (https://en.wikipedia.org/wiki/AES_instruction_set).
