https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=272944 --- Comment #5 from jSML4ThWwBID69YC@protonmail.com --- (In reply to Mark Johnston from comment #4) Hello Mark, Please see the emailed video. It shows a sixty second iperf3 test with the output of top in the jail, and on the host. This test used a local network Vlan for communication. So far as I can tell, the performance is not impacted by using a Vlan on Vnet. I tried using the PCBGROUP, and RSS options in the kernel configuration. The kernel builds and installs fine. After reboot, I was able to ssh back in, but it seems most networking is broken. Trying Iperf, Curl, Fetch all fail with timeouts both on the host system and in a jail. Removing those options, rebuilding the kernel and rebooting makes everything work again. -- You are receiving this mail because: You are the assignee for the bug.help
