Wow, you must be sending terabytes of stuff through ssh. :-)
Assuming the request is legit:
1. Disable compression if you don't need it.
2. Try another crypto protocol. Years ago, when this problem was real
:-) (sorry, no offense), I used to force blowfish instead of whatever
crypto was default back then, and it produced a significant decrease of
CPU usage on those Pentium II processors.
ssh -c blowfish-cbc hostname
I don't know which protocol is fastest nowadays, but I guess you can do
a quick test and find out.
There might be some security implications for using a different crypto
protocol, but you need to figure that out yourself.
