I notice high CPU usage on xt_ein on ROS 7.20.2
It’s endpoint independent nat. (Xt is the abbreviation for extensions to iptables - the firewall subsystem, ein stands for endpoint independent.)
There were several reports of ein taking an inordinate amount of cpu, bug as fasr as I can tell, the reason is unclear.
I see, I try disable “endpoint independent nat” and see what happen
