I did a quick file download test on the LRO-enabled device (forwarding is turned on) and there's no perceive drop-off in forwarding performance.
The test is very unscientific (over the Internet) as I don't have access to a local test bed where I can do more in-depth testing. Sysctl LRO stats gave me these: dev.igb.0.queue0.lro_queued: 53 dev.igb.0.queue0.lro_flushed: 53 dev.igb.0.queue1.lro_queued: 121 dev.igb.0.queue1.lro_flushed: 120 dev.igb.0.queue2.lro_queued: 14895 dev.igb.0.queue2.lro_flushed: 8200 dev.igb.0.queue3.lro_queued: 77 dev.igb.0.queue3.lro_flushed: 76 Just curious on why flushed and queued numbers did not seem to match. ihsan On Jul 8, 2012, at 12:26 AM, Jack Vogel wrote: > Because of problems with forwarding when it was turned on, however this has > recently been fixed supposedly, if someone using the driver in an > environment > with forwarding could verify that there is no problem with it enabled I'd > be happy > to change it to be on by default. > > Jack > > > On Sat, Jul 7, 2012 at 9:01 AM, Ihsan Junaidi Ibrahim <ih...@grep.my> wrote: > >> Hi folks, >> >> Just curious is there a reason why LRO isn't turned on by default for >> igb(4) like for other capabilities? >> >> I have a couple of 82575EB igb devices and LRO had to be turned on >> manually. >> >> Thanks._______________________________________________ >> freebsd-net@freebsd.org mailing list >> http://lists.freebsd.org/mailman/listinfo/freebsd-net >> To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org" >> > _______________________________________________ > freebsd-net@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-net > To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org" _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
