<body>If you want to test speed, it's probably a good idea to use multiple
files to multiple machines at the same time, 'cause other factors can cause
it to be slower than it should than just your machine. Doing two or more
transfers at once should give slightly more accurate results. Other random
things can slow the transfer down as well, like interference--cat 5 is extremely
susceptible to that. Collisions would slow it down a little, but I doubt
you would notice it. I think it's unlikely that they would be responsible
for a 4mb/s drop.<br><br><a href="mailto:brian@cbiowa.com">brian@cbiowa.com</a> wrote:<br>

The reason I even had the question is because I wanted to test out the
speed of my network. I used an extremely big file and ftp. I expected
somewhere around 10M/s and I got 6M/s. This was what looked like an
obvious place to start looking .
