How about something more down to earth for a moment. I was curious about a comment ( by Jan ? ) in which he says that using aes256-cbc as the Cipher would just generate a lot of CPU usage. I was curious to see .. well .. how much ? Turns out he is quite right. A lot of CPU usage for a daemon. Take a look at this simple test I just did. I setup my sshd_config such that Ciphers was aes256-cbc only. I then ssh into the server and I run find on my home directory. My home directory has a ton of source code in it and the find proicess runs for about 60 secs or so. A perfect time to ask "how much CPU is sshd using" ? this is from a serial console as root so no interference from that. # prstat -R -m -c -n 5 5 12 PID USERNAME USR SYS TRP TFL DFL LCK SLP LAT VCX
