Yes, but that's what having 8192 2KByte descriptors handy is for... (that's 16MB of buffering). > > If your PCI implementation won't keep up with gigabit speeds, you'll just > go slower. :) Most newer systems (e.g. 440BX) shouldn't have any trouble > doing a reasonable amount of speed over gigabit ethernet, though. Typically I don't see higher than 60 or 70MB/s real throughput on most systems. -matt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
