https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=276760 --- Comment #20 from Michael Tuexen <tuexen@freebsd.org> --- (In reply to vova from comment #19) That is really interesting. If I summarize it correctly, we have: vtnet: 14.3 stable/14 send w/o offloading 789 772 send w/ offloading 485 523 recv w/o offloading 1938 2052 recv w/ offloading 719 972 vnet: 14.3 stable/14 send w/ offloading 1595 1624 send w/o offloading 1425 1584 recv w/ offloading 166 1813 recv w/o offloading 1504 1085 (stable/14 of October 9th; Speed is in Mbps) What is your setup? I would like to be able to reproduce this locally? Are you just running the speedtests in a VM using vtnet? Or are other VMs doing forwarding involved? What is your setup with the vnet? Which interfaces are used in that case. Thanks for testing! -- You are receiving this mail because: You are on the CC list for the bug.
