      When connecting a Truenas server to my Pfsense box with SFP+ through my 10gig switch on the same LAN running iperf I am getting around 5.79Gbps.

      Can anyone tell me if this is normal? I expected to see 10Gbps if on the same LAN or is this a PFsense limitation with the software. Both machines are Xeon multi cores with 32GB plus of RAM.

        That's impossible to say without knowing what performance the computers are good for. Try connecting them directly.

        PfSense running on Qotom mini PC
        i5 CPU, 4 GB memory, 32 GB SSD & 4 Intel Gb Ethernet ports.
        UniFi AC-Lite access point

        I haven't lost my mind. It's around here...somewhere...

          Never test it that way anyway. Pfsense is meant to be router, and route traffic - not process traffic..

          test through pfsense..

          truenas -- 10g -- pfsense -- 10g -- other box..

          once you have validated what

          truenas -- 10g -- other box

          Can do..

            Yes, iperf can be useful on the firewall to prove a link speed but not for absolute values testing.
            It shows your are connected at >1Gbps here for example but that value will always be lower then testing between two hosts through the firewall.

              Weh I couldn't face booting up my spare workstation and installing 10gig card and having to have 2 keyboards etc etc. I guess its the only way to check all my hardware is working as it should, so I will link 2 workstations together later and blast them with iperf and hopefully get near 10gig.

              Thanks peoples

                Just booted Trunenas on a Dell R220 Xeon 1220-V3 16GB ram and linked directly to Dell workstation with OM3, running windows and Xeon 1230V5 16GB ram.

                546+ SFP+ mellanox cards

                Results

                [ 1] local 192.168.2.1 port 57829 connected with 192.168.2.2 port 5001
                [ 2] local 192.168.2.1 port 57830 connected with 192.168.2.2 port 5001
                [ ID] Interval Transfer Bandwidth
                [ 2] 0.00-10.03 sec 5.57 GBytes 4.77 Gbits/sec
                [ 1] 0.00-10.03 sec 5.44 GBytes 4.66 Gbits/sec
                [SUM] 0.00-10.01 sec 11.0 GBytes 9.45 Gbits/sec

                Happy with that.

                This is interesting -

                I now did the same iperf transfer but this time removing the OM3 fibre and using DAC 2M copper and here are the results -

                [ 2] local 192.168.2.1 port 62289 connected with 192.168.2.2 port 5001
                [ 1] local 192.168.2.1 port 62288 connected with 192.168.2.2 port 5001
                [ ID] Interval Transfer Bandwidth
                [ 2] 0.00-10.01 sec 6.33 GBytes 5.43 Gbits/sec
                [ 1] 0.00-10.03 sec 4.61 GBytes 3.95 Gbits/sec
                [SUM] 0.00-10.01 sec 10.9 GBytes 9.39 Gbits/sec

                I ran both tests a few times and DAC is consistently slower transfer rate.
