There again, any network installer worth their salt will test the cable when in-situ, after the 'dust' has settled... Fastest I've seen on my setup (doing anything useful) is around 9Mb/sec going from my WinNT box (with Intel Pro 100B) to my FreeBSD -current box (also with Pro 100B). So far, transfers from FreeBSD to WinNT are _always_ slower than transfers from WinNT to FreeBSD - which considering the hardware and write-overhead etc. - you would have though the opposite should be true... I guess NT ain't a great operating system after all... <no kidding? :)> -Karl To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
