      @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.

        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 Thanks
          This solves the trouble
          The solution is https://www.doitfixit.com/blog/2020/01/15/slow-network-speed-with-hyper-v-virtual-machines-on-windows-server-server-2019/

          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

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

                      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?
