HP T5740 gigabit over PCIx
-
That's really just limited by your WAN speed then. A more interesting test would be between two internal interfaces, both on the PCI-X card.

I was looking at ways to test that. I came across iperf so I am going to try it out later. I will post my results

iperf results (This is between a client and pfsense) I am doing this remotely so I only have access to pfsense and the client I am typing on now.
Pfsense was the server.

Looks like the CPU is the bottle neck. Ran the TCP test for 200 seconds it transferred 6.83 Gigabytes of data at 293Mbps and the CPU was maxed out.

Interesting thanks. Be interesting to see how that compares with running thd server and client on separate mchines behind pfSense on separate interfaces.

My plan was to try that when I get home. I will let you know.

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?
