I did some performance testing comparing pfsense and opnsense on idential hardware, and out-of-the-box configuration. On my Atom 1.6ghz dual Intel nic router I was able to get near line-speed gigabit NAT from pfsense, while opnsense maxed out around 825mbps. I spent only a couple of hours with the test, and quickly decided switching off pfsense wasn't worth it for me.
