i think on CRS a 5-10% cpu usage with no traffic its normal, i think is the cpu used to manage switch features
use tools -- profile to identify the source of that your load
Thanks for your reply Chechito.
I actualy can see exaclty the same behavior(1'st Post):
"I have a new CRS upgraded to 6.6 and firmware 3.10. With no load on the box just running the profiler it has 5 to 7% CPU usage from "management". "
only difference is the version, mine is on the last bug fix version.
