http://vincent.bernat.im/en/blog/2011-ssl-benchmark.html Interesting test results comparing and analyzing SSL performance. Using right combination of software and proper tunning, you can get up to 14000 TPS (re-shake every 80 requests) on HP DL 380 G7, with two Xeon L5630 (running at 2.13GHz for a total of 8 cores), without hyperthreading, using a 2.6.39 kernel (HZ is set to 250) and two Intel 82576 NIC.
