https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=234624 --- Comment #1 from Nick <freebsd@aoeu.uk> --- Hi, I've done some additional testing: -Failing over to the igb interfaces doesn't show any problems with TSO enabled or disabled, so this is probably specific to ix -Dropping the MTU to 1500 has no effect -Removing an ix interfaces from its lagg and configuring an untagged interface directly on it doesn't shows significantly but improved TX performance, however this is seen with TSO enabled and disabled. I haven't managed to rule out the switch configuration as the cause of this yet, as I don't normally have any untagged ports. I'll update in a bit when I've done some more testing with the untagged interface configuration. Kind regards, Nick -- You are receiving this mail because: You are the assignee for the bug.
