      My pfsense box just recently started acting up and I am getting low throughput through it (10-20Mbps where I should be able to get 150).  I am not using a VPN.  I tried a direct connection to my computer through ISP modem and I get the full 150, so it is not my ISP.

      I am using a realtek NIC though, could that be the issue, will a bad NIC cause low throughput?  I have had the box for about 2 years now and it was working just fine up until about a week ago.  I have tried the standard documentation regarding low throughput and none of the suggested fixes work.  I have also ensured there is no traffic shaper turned on.  I have even reset the box to defaults and it still has low throughput.

      Any recommendations or things i can try to do to fix this issue?  Thanks.

        Check Status > Interfaces for errors. could be a duplex mismatch though on gig-e that is less likely than on 100BaseTX.

          Checked the Interface Status.  No in/out errors or collisions on either of the interfaces.  Is it possible a bad NIC can cause this? My box is set up as it has one NIC on the built in mobo and another PCIE NIC (the cheapo rosewill realtek).

            Anything's possible though I would expect errors somewhere. Just get Intel and see I guess.

            You can also install the CLI speedtest.

            ssh in and:

            pkg install py27-speedtest-cli
            rehash
            speedtest

            Retrieving speedtest.net configuration…
            Retrieving speedtest.net server list...
            Testing from Cox (158.51.0.100)...
            Selecting best server based on latency...

            Testing upload speed..................................................
            Upload: 8.79 Mbit/s

            That will test from the WAN port eliminating LAN-side issues.

              Ok great, I did this and I am getting.

              So these are my max ISP speeds.  This means that the WAN is ok but my LAN card is buggered I assume.  The LAN card is my cheapo realtek.

                You can install the iperf package and iperf2 on a LAN host and test that leg. I'd just search how to use it.

                You generally run a server or client on the firewall and the opposite on a workstation.

                It always sends from client to server so switch roles to go the other way.

                The package will add Diagnostics > iperf to the menu.

                  There are a lot of problems with realtek cards using built in freebsd driver. Just read https://forums.freebsd.org/threads/55861/ or replace it with Intel as suggested already.

                    Update.  I have replaced the NIC and all is good again, it was caused by some failed hardware.  Anyways I had to replace it with another realtek because my little box is so small I need super low profile card and I could not find an intel one that was small enough, anyways it I will know what to replace if this happens again.  Thanks for all the help!
