On my CentOS v5.2 server (dual Pentium4) the OpenSSH daemon stands out
as being the most CPU-intensive of the applications running, It's used
176 minutes of CPU time in the last 2 days alone.
Is there any way to lower the CPU utilization without compromising
security? (I.e. without using a less processor-intensive
I'm getting the CPU use figures from top, so there no fine-grained info
on exactly what code is taking so much time. I'm assuming that the
bulk of the time is spent in the OpenSSL libraries.
Is there some hardware add-on or processor-specific optimization that
would reduce the CPU load incurred by OpenSSH?
