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).
