      Are you using those interfaces directly? VLANs? VPN?

      Does the CPU load (per core) look OK?

      Any errors on the NICs?

        @dredex same here; speed test in front of PFSense about 100 Mbps, behind about 10 Mbps
        No error anywhere, performances are normal (no CPU peak or anything showing performance issue)
        It was perfect before upgrading to 2.6.0

          Did some further testing and the problem is with my PC, tried on another one HERE and the speeds are fine, probably smth with Win 11, NIC or drivers....

          Sorry for misleading, I should have tested more before posting...

            Yep, with broadband speeds these days, hardware can often make a difference. Before getting the computer described in my sig I had an old HP compact desktop computer. It would do better than 500 Mb down, but the new computer did much better. I've even seen over 900 Mb on my 500/20 connection.

            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...

              to be clear this has nothing to do with hardware or OS
              No changes have been done on the network and all devices (Windows or Android) have the same issue - so Windows can not be involved here - especially when WinUpdate has been done 2 days before the PFSense upgrade and no issue after it
              This appears immediately after the upgrade from 2.5.2 to 2.6.0

                I have deployed a new PFSense running 2.5.2 and the network connection is now as expected; speed test showing 100 Mbps as before the upgrade to 2.6.0
                This confirms something is wrong with 2.6.0

                  @benoithamet What network cards do you have in the problem router?

                  Pre-2.7.2/23.09: Only install packages for your version, or risk breaking it. Select your branch in System/Update/Update Settings.
                  When upgrading, allow 10-15 minutes to restart, or more depending on packages and device speed.

                    @steveits PFSense is virtualized on Hyper V so it using vNIC
                    how this is relevant? there has been no change in the network configuration before or after PFSense upgrade
                    And the test with a PFSense running 2.5.2 has been done in the exact same configuration

                      PFSense is virtualized on Hyper V

                      There have been a few threads this week about Hyper-V, such as
                      https://forum.netgate.com/topic/169884/after-upgrade-inter-v-lan-communication-is-very-slow-on-hyper-v/1

                      I haven't looked at it but it's always possible a FreeBSD driver changed between FreeBSD versions.

                        @steveits Thanks
                        This solves the trouble

                        Interestingly I never had any trouble until this upgrade

                          So specifically disabling RSC in the vswitches brings back the expected throughput for you?

                            @stephenw10 yes, on both LAN and WAN vSwitch
                            if only one still have the RSC enabled, the connection speed drops to 10% of the normal one

                              Interesting. Thanks for confirming.

                                @stephenw10 no thank you; I would not have thought about the hypervisor as I did not had any network trouble before

                                  @benoithamet I had the same problem after update to 2.6.0 ... Thank you for this post, it was a great help to me.

                                    so, what's the fix for those of us on bare-metal and not VMs?

                                      To throughput issue after upgrading to 2.6?

                                      From what? On what hardware? What sort of slow down are you seeing?
