It shows a sixty second iperf3 test with the output of top in the jail, and on the host.=20 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.=20 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, b= ut 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. --=20 You are receiving this mail because: You are the assignee for the bug.=
