      Hi,

      I have the following HA - Setup:

      2x HP Proliant DL360 gen9 with 1 onboard LAN ( HP Ethernet 1GB 331i), 1 PCI-E LAN (HP Ethernet 1GB 331FLR) and 1 PCI-E LAN (HP Ethernet 10Gb 560SFP+).
      pfSense Software 2.4.5 p1

      I have configured different VLANS on these interfaces. The routing, CARP, etc. works so far. Then I wanted to test the speed of each interface. The iPerf3 test gave the following results:

      From 1GB interface (HP 331i) to 10GB interface (HP 560):

      From 10GB interface (HP 560) to 1GB interface (HP 331i):

      As you can see, we have significantly worse performance from the 10GB to the 1GB interface than vice versa. However, the speed from 1GB to 10GB does not satisfy us either.

      I did an iperf3 test directly from the pfSense to the individual targets and found the following values:

      From the pfSense (1GB interface) to the first destination:

      From pfSense (10GB) to second destination:

      Does anyone have any idea how i can fix this? We would be satisfied with a result close to 1GB.

      Thanks in advance.

      Kind regards,

        don't test TO or FROM pfsense ... that is pointless.
        it's a router. run the tests THROUGH pfsense with a client/server on each end

          Sorry for the misunderstandings. We have tested the throughput with a client/server.

          First test Client/Server -> pfSense in (1GB) -> pfSense out (10GB) -> Client/Server

          Second test Client/Server -> pfsense in (10GB) -> pfSense out(1GB) -> Client/Server.

          third test iperf pfSense out (1GB) -> Client/Server.

          fourth test iperf pfSense out(10GB) -> Client/Server

          I hope it is better to understand.

          Thank you for your help.

            @kotty try the tuning for your specific cards/drivers
            the 331i appears to be some sort of broadcom chipset
            the 560 seems to be an intel chipset

              Thank you.

              I have already gone through this post. This has improved the performance. I had problems with packet loss. After I went through the tuning guide, it got much better. But now there are still the performance problems. Could it be a problem with the network cards?

                I don't have similar hardware.... Might be a lot of things.

                Cabling/switch/driver/....

                  Hi,

                  I have some news. After replacing the Intel 10GBE network card with an Intel X722-DA2 (ixL Interface), my performance problems are gone. But there is a new problem. When testing the 10GB performance I only get a speed of 2.7Gigabit. Here is an excerpt from iPerf3:

                  With the command "top -p CC" I see that the test uses only one CPU Core to 100%. However, this only happens when testing the 10GB connection. 1GB tests are distributed over all cores. As it should be. Is there a command or a way to set the pfSense to multicore for 10GBE connections?

                  Thanks in advance.

                  Kind regards,
                  Kotty
