https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D258133 Bug ID: 258133 Summary: toggling TSO fixes latency/slowness Product: Base System Version: 13.0-STABLE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: nbari@tequila.io The main interface in the system is igb0, it has a vlan0 interface with oth= er gateway (fib 1) in where in theory TSO is enable by default: vlan0: flags=3D8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 14= 00 =20=20=20=20=20=20=20 options=3D4600703<RXCSUM,TXCSUM,TSO4,TSO6,LRO,RXCSUM_IPV6,TXCSUM_IPV6,NOMAP> I started to notice some latency issues on the VLAN and by just enabling ag= ain TSO the problem was fixed: ifconfig vlan0 -tso=20 ifconfig vlan0 tso Is there a way to ensure that TSO is always enabled also for newly created interfaces or probably by enabling/disabling TSO fixes other issues? --=20 You are receiving this mail because: You are the assignee for the bug.=
