For 100Mbs links, well, ... let's just say it appears to have a lot of overhead. I'm not sure whether it's Matt Thomas' de driver which is the issue (certainly, the driver code needs some simplification) or if ALTQ requires the send interrupt to be triggered so that he knows a packet has drained. FWIW. BTW: Kenjiro: Mighty fine work. -scooter To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
