Its about the CPU cost of the crypto. I was once told the number of CPUs required to do SSL on web search (which I have now forgotten) and it was a bigger number than you'd expect -- certainly hundreds.
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." -- Niels.
