      Hello everyone, I have a question I hope you can help me, I have a pfsense in version 2.6 virtualized in Hyper-V and the download speed of the computers on the LAN is 3mb when I have 1gb symmetrical, I go back to version 2.5.2 and the speed is 867 symmetrical. It only happens to me on a virtualized pfsense on a physical pfsense works fine.

        It is a known issue with a setting in Hyper-V. Read all the posts in this thread for more info: https://forum.netgate.com/topic/169884/after-upgrade-inter-v-lan-communication-is-very-slow-on-hyper-v/80.

        Best guess is some change in FreeBSD 12.3 tickled the bug with a setting Microsoft added to Hyper-V some time back. Specifically this post in that thread helped some users recover their speed: https://forum.netgate.com/topic/169884/after-upgrade-inter-v-lan-communication-is-very-slow-on-hyper-v/37. The problem seems to be with the RSC (Receive Segment Coalescing) setting in the Hyper-V vSwitch.
