High CPU usage with tunnel
-
Hi all,
I've been running multiple VPN tunnels with pfSense and if seems like the CPU usage is much higher then when I was hosting the tunnels on a box behind the firewalls. The pfsense box is a nice dual-core mid-grade CPU box, about on par with what used to be hosting the tunnels, but the process is taking about 20-30% CPU in top on the firewalls, as opposed to ~5% on the original machine. One config difference is going from shared-key to PKI, but I'd be surprised if that meant such a dramatic jump in processing requirements. I'm also not too terribly sure how to go about poking any deeper on this. Any ideas?
Thanks!
