To give you some numbers, my server accepts less than 100 ssl clients per second while it accepts more than 10k tcp clients per second with the same service logic behind save for the transport types. I tested the same scenario with a server written in c for comparison and got numbers about 1k/s in ssl and 10k in tcp.</div>
