--- Comment #27 from [email protected] --- Created attachment 263708 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=263708&action=edit results of vtnet output Thank you for all the efforts here Michael, I (and I am sure the wider FreeBSD community) appreciate it greatly!! TLDR; maybe a problem with LRO still ? I set up 2 VMs R14 and R15 both with 2 interfaces and am using iperf3 to test speeds R14 and R15 share 192.168.122.0/24 as a common subnet iperf3 between 192.168.122.0/24 looks good at expected speeds doing both iperf3 -R -c 192.168.122.3 and iperf3 -c 192.168.122.3 gives between 15Gb/s and 18Gb/s which is great >From R14 to an outside server on gigabit gets about gigabit in both directions which is typical >From R15 to an outside server on gigabit gets about gigabit in both directions which is typical from R15 that is routed across R14's 192.168.122.0/24 network however, I am getting 2-3Mb/s If I ifconfig vtnet0 -lro ifconfig vtnet1 -lro on the R14 box acting as a router, all works at expected speeds If I reverse the jobs or R14 and R15 so that R15 acts as the router, it is the same issue. I have to do both interfaces for both directions to work otherwise just one direction gets full speed. -- You are receiving this mail because: You are the assignee for the bug.
