--Apple-Mail=_E29563A1-48A5-410C-A19F-5F15BA3125E7 Content-Transfer-Encoding: quoted-printable Content-Type: text/plain; charset=us-ascii I haven't played with lagg+vlan+bridge, but I briefly evaluated XL710 = boards last year = (https://lists.freebsd.org/pipermail/freebsd-net/2015-October/043584.html)= and saw very poor throughputs and latencies even in very simple setups. = As far as I could figure it out, TSO/LRO wasn't being performed = (although enabled) and so I ran into packet-rate issues. I basically gave up and went with a different vendor. FWIW, the XL710 = boards in the same machines booted into Linux performed fine.
