Hello...  I have been doing some testing with 10Gb ethernet cards.  The test
consists of downloading a 400MB file using wget.

If I use just the "wget" command with no options, I get a transfer rate of
about 400 MB/s.

If I use the "wget" command with the "--progress=dot" option, I get a transfer
rate of about 150 MB/s.

Is this as it should be?  I recognize that using the "--progress=dot" option
means that more info is written to the screen, but should this be included in
the calculation of transfer rate.  Thoughts?

Note:  The way we ran into the problem is that our tests actually write the
wget output to a file, and this forces the use of the "dot" reporting style.

Thanks.
