Actually faster than just receiving the traffic. I guess it's definitely CPU bound then.
A further interesting test would be to enable IP fastforwarding. That may or may not have a dramatic effect on traffiic that is passed through the box but not terminated there.
It's enabled in System: Advanced: System Tunables:. Set the net.inet.ip.fastforwarding tunable to 1. You may have to reboot to activate that. Be aware that setting that value WILL break IPSec pass-through so if you need that disable it again after the test.Steve

It seems that maybe I am wrong. The CPU will max out only when using the pfsense box as the server. I wasn't watching it when looking at the above tests. I set the fast-forward option and get about the same speeds. I believe the best was 394Mbps. The CPU only reached 67% and only for a moment the average for the 20 second test was probably 63%. So I am guessing that the PCI bus? is limiting the card to ~400Mbps?

Yes. You might expect a maximum throughput of half the bandwidth which would be ~512Mbps however that doesn't allow for any return traffic, error-correction, ACKs etc. Did you see any reduction in CPU use with IP fastforwarding enabled?

Pictures of the box. it was a pretty tight fit. I had to cut the SATA cable strain relief so it would bend enough when the PCI right angel adapter pressed on it. Tried uploading these pictures to this post but they were too big.

Looks great - one question - where did you get the power from to run your fan?
