False: https://www.imperialviolet.org/2010/06/25/overclocking-ssl.html
"On our production frontend machines, SSL/TLS accounts for less than
1% of the CPU load, less than 10KB of memory per connection and less
than 2% of network overhead. Many people believe that SSL takes a lot
of CPU time and we hope the above numbers (public for the first time)
will help to dispel that."
