      After two days of pulling hair trying to restore the config from the 6100 to the R230 (thanks pfBlockerng for borking the firewall in a restore :/ ) I have the R230 up and running. And the results are really quite poor.

      My ISP has an iperf3 server three hops away from me. Details below on how I run iperf3 tests.

      6100 - ~9.6Gpbs / sec
      R230 - ~692 Mbits/sec

      Intravlan
      6100 - ~2Gbps/sec
      R230 - 1.61 Mbits/sec ... in fact, after the first few packets, it drops to 0Mbits/sec

      For baseline, same hosts on subnet (vLAN): 9.27 Gbits/sec

      DETAILS

      Hardware

      pfSense box

      • Dell R230 Xeon E3-1270 v5 @ 3.6GHz
      • 16GB
      • 2x Samsung 850 SSD in ZFS redundant pool
      • HP NC523SPF NIC in PCIe port 2 (which I believe is full 16 lanes)

      switches & cables & optics

      • unifi aggregation 10G switches
      • Intel 850mm SFP+ optics
      • mm patch cables (same ones used to get faster results with 6100)

      Testing
      iperf3:
      iperf3 -c server.fqdn.foo.bar -P 10
      iperf3 -c server.fqdn.foo.bar -P 10 -R
      iperf3 -c server.fqdn.foo.bar -P 10 -6

      NOTE while I have tried testing right from pfSense, all posted results are from a LAN host to another host and as indicated above the LAN host has no problem sending/receiving 10Gbps traffic.

      system monitoring:
      top -aSH

      pfSense

      • WAN - static IPv4, dynamic IPv6
      • Hardware Checksum Offloading - tried both on and off
      • Hardware TCP Segmentation Offloading - tried both on and off
      • hn ALTQ support - on

          What NIC chipset/driver is that? Those numbers seems really low.

          Make sure you have multiple queues in attached for each NIC.

            @spacebass It’s your 10Gbe NIC that’s causing issues.

            I have worked with HPE hardware for 20 years, and the NC523 card is a dud. I can’t quite remember the details, but the card took more than a year and half worth of Windows driver updates to it’s Qlogic controller to reliably deliver about 2Gbits performance. Until then it fluctuacted wildly and stalled to zero any time you tried to push it above about a gbit.

            I can only guess how bad the driver state with FreeBSD is, but i’m quite sure the card is your culprit. Ditch it and get a Intel based 10Gbe NIC that has good driver support in pfSense.

            Love the no fuss of using the official appliances :-)

              Thanks @stephenw10 for replying!
              It is a Qlogic 3200 which uses the qlxgb drivers.

              I applied the following tunables (but no real change)

              kern.ipc.nmbjumbo9=262144
net.inet.tcp.recvbuf_max=262144
net.inet.tcp.recvbuf_inc=16384
kern.ipc.nmbclusters=1000000
kern.ipc.maxsockbuf=2097152
net.inet.tcp.recvspace=131072
net.inet.tcp.sendbuf_max=262144
net.inet.tcp.sendspace=65536

              Make sure you have multiple queues in attached for each NIC.

              Can you elaborate? I'm not using traffic shaping and that's the only context I have for queues

                @keyser the good news is that I have Intel cards on order...

                That said, I have a ton of these HP cards and have no problem getting 10Gbps on Linux-based boxes...it could be drivers, but the qlxgb in FreeBSD is pretty tried and true.

                  Ah I wasn't sure if ql1 there was that. Ok then at the very least I'd start by disabling all the hardware off-loading options. But if you know exactly which driver it is you can start looking for known bugs/workarounds.

                  But, yeah, if you can use an Intel NIC, you should.

                    @stephenw10 thanks - if I want to add the full (supposed) 8 queues, how would I go about it?

                      How many queues are you getting?

                      It's probably a sysctl or loader tunable for that driver. Without having one to test it's difficult to say.
                      Try sysctl hw.ql or maybe sysctl hw.qlxgb and see what values exist.

                      Also check sysctl dev.ql.0

                        that's the key ... no mq options there though and I dont see any listed in the readme.txt in the driver's source.

                        I'll wait for the Intel NIC and see what I can get out of that

                          How many queues is it using by default? If it's just 1 that would explain the single threaded performance.

                            @stephenw10 I'll fire the box up and check ... just curious, what am I looking for in the output of sysctl? I didn't see anything with 'mq' or 'queues' in the output when I first checked.

                            perhaps related - what does it tell us that I get closer to 4Gbps with the -R flag on iperf3 (eg inbound) vs 2Gbps without the flag?

                            I'm not overly determined to make this Qlogic card work, but this is a really good learning opportunity and I'm enjoying the process.

                              You might have more Rx queues than Tx queues for example. Most drivers show that in the boot logs but I'm not sure qlxb does. vmstat -i may also show it.

                                Thanks for the continued help...

                                Here's what I see

                                I'm having trouble finding much documentation online for this driver... would snd_pkt_thres be the number of threads it is able to or currently using for the outbound queues?

                                Here's the output from a TrueNAS box with the same card which has no trouble moving 10Gbps traffic:

                                  Mmm, so likely those are the default values. There should be a description of each tunable if you run: sysctl -d dev.ql.0

                                      Well at least 4 IRQs for ql0 there. Does vmstat -i show those?

                                      Nothing about queues there I agree. That's the sort of setting that would usually be a loader value though. Those are usually shown in hw.ql but only values that are set are shown.

                                        Intel X520-da2 update

                                        tl;dr better performance for sure, but still not 10Gbps. 8 CPU cores, each NIC using 4 queues.

                                        I'm increasingly of the opinion that even with a beefy CPU pfSense just doesnt like doing 10Gbps 😂

                                          Pretty exactly the same on my end. I will now try to get in touch with our ISP again to make sure it's not their core router being the culprit here!

                                            Are you guys using SATA on your hardware??

                                            Remember there is a 6gbit/s limit to that when writing to the disk sybsystem.

                                            And I bet that is what you see.

                                            IN short... your NIC is pushing the limits of the disk subsystem.
