Testing after the dust has settled and while it is in use is different since conditions do change. The testers only tests for continuity, not the impedance or any other electrical properties of the cable. > 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).

What about from FreeBSD to FreeBSD? =) Cheers, Vince - vince@MCESTATE.COM - vince@GAIANET.NET ________ __ ____ Unix Networking Operations - FreeBSD-Real Unix for Free / / / / | / |[__ ] GaiaNet Corporation - M & C Estate / / / / | / | __] ] Beverly Hills, California USA 90210 / / / / / |/ / | __] ] HongKong Stars/Gravis UltraSound Mailing Lists Admin /_/_/_/_/|___/|_|[____] To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
