The Apple TB bridge has known performance issue and some BCM controllers have a work-around to mitigate it. The work-around is not enabled by default so I'm interested in bge(4) performance numbers on your box. If you can't get more than 920 ~ 930Mbps(950Mbps or higher with jumbo frame) please let me know. I didn't enable the work-around yet since it will hurt other BCM controllers when TB bridge is absent. _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
