https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D219672 --- Comment #6 from Maxim Masiutin <max@ritlabs.com> --- I agree with your conclusions, but I didn't make the tests that you have suggested : (1. see good performance with LRO turned on and scp a large fil= e to the appliance and 2. see ICMP "need to frag" with LRO turned on and scp to a machine on the remote side.) Since when I use pfSense as a router, and when I ran speed tests on virtual machines that used pfSense as a router, and download speed almost didn't suffer, but upload speed dropped from around 400 MBps to around 0.5 MBps, I suspect that your conclusions are correct. So I agree with you that it was a misconfiguration, not a bug. But I didn't make the tests that you have suggested. I have contacted pfSense developers and asked them to change the notice in = the configuration panel in pfSense. Currently, there is a notice saying that LR= O is disabled by default because "most drivers have bugs". I have asked them to change this to "LRO should only be enabled on an end point". I am sure that= the description of the LRO user interface was the cause of all problems that mi= sled me. I will watch future versions of pfSense and will remind them if they won't change the notice. Don't get me wrong, I'm just a simple user, not a professional sysadmin, and I'm not skilled enough, for example, to see ICMP "need to frag" with LRO tu= rned on and scp to a machine on the remote side. I would have suggested to close this bugtracker entry. Thank you very much again for your help. --=20 You are receiving this mail because: You are the assignee for the bug.=
