How do I figure out what's falling behind? First of all, the transmit threshold could stabilize and you'd be ok. You should have a fast processor, a good PCI bus without a lot of other stuff on it. Video cards eat PCI bandwidth. A fast FSB is good too, because packets transfer in and out of memory. Just bad PCI timing settings in the BIOS can problems like this too. > Regards > +------ > Dan Larsson | Tel: +46 8 550 120 21 > Tyfon Svenska AB | Fax: +46 8 550 120 02 > GPG and PGP keys | finger dl@hq1.tyfon.net > > > > > To Unsubscribe: send mail to majordomo@FreeBSD.org > with "unsubscribe freebsd-stable" in the body of the message > Tom Uniserve To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
