      Yeah, testing directly from or to the firewall is only really useful for fault locating. You can compare the results from two different interfaces for example but absolute values are almost always going to be lower that what can routed through it.

      That said those values do seem low.

      Also you will not see 10Gbps through that unless maybe you used jumbo packets etc. I would expect somewhere in the 3-4Gbps region but there are many variables.

        Yes, the values are very slow. If I hook up my home network to it and test to my web server through the PFSense Firewall, here is what I get:

        Where as if I connect to it directly:

        (I am not sure why its not showing closer to 3-4gbps, but its a newer server, have not looked at mtu or anything)

          I assume you are testing over a 1G link there. igb NICs?

            Yes, both are 1Gb NICs and a a short Cat5e cable between the two.

              But are they igb NICs as opposed to em or re etc?

                I guess I don't know what IGB vs EM vs RE are.
                But I do see that the nics are IGB

                  Ok they're igb. They pretty much had to be unless you had added more since the C2758 has 4 igb NICs built into the SoC.

                  You should be seeing significantly more than that. I would check the output at the command line of top -aSH whilst testing.

                  Make sure you have all off loading disabled in Sys > Adv > Networking.

                  Check vmstat -i shows interrupt loading from each NIC spread across the cores.

                    How do you expect to get more than 1Gb out of 1Gb NICs? You are going to need 10G to the ISP.

                      @Derelict because when connected direct to the network I’m on 10gbps. Not through the router.

                        Non-trivial to set up a lab like that. is virtualization involved? What switches etc?

                        Going to need more information. Guarantee the C2758 is capable of forwarding faster than you are seeing there, barring some strange issue with your particular unit.

                          No, Virtualization is not involved, I have the nic in my personal PC directly connected via a cat6 cable to the device.

                              The igb NICs are all 1G. You have 10G NICs in that firewall too?

                                Not on this one, this is my test device. But My point was that I was getting very slow speeds on this device. The device that I will be building is 10gb device. I was also explaining that if I hook up my PC direct to my existing non-test network (all 10gb), I do get a faster speed test.

                                  Ok, so we are still looking at the ~250Mbps limit on a 1Gbps connection.

                                  So do the tests I asked about here and we can check the results.

                                    Any update to this thread? im having the same problem with the bandwidth speed when using pfsense.

                                      You should start a new thread for this and detail exactly what you're seeing and what you have done.
                                      There are numerous reason you could be seeing less throughput that you expect. The chances you are hitting the same issue as the OP in this thread are low.
