[strongSwan] Visibility on usage of a strongswan/ipsec server

[Andrew Foss]

Folks,

I am pushing a ~200mb/s though my ipsec server, but when I look at cpu 
with top or load average with uptime, the machine looks like it is idle. 
I am guessing that the work is being done in the kernel, but I still 
need to measure how much of the machine's capacity is being used by ipsec.

Is there some other better place to look to see how much of the system 
strongswan/ipsec is occupying?
