I would guess the gigabit switch vs my cheapo
100Mb/s switch would make that sort of
difference. You have to do the test with the same
hardware, same server, same switches otherwise
you have no relative comparision that's valid.
The server could make a huge difference also. Ftp
servers are kind of kludgy in the way that they
decide on how to dispatch packets. I'd guess that
if you put an intel card into the box you'd get
similar relative differences in throughput.

Its not a good test anyway, but you have to
simplify things for jerry and the gang. A better
way to test is to generate a consistent load and
look at CPU usage. The efficiency of the server,
windowing, etc will all affect an FTP transfer
too much to use it as a complete test. The
seemingly tiny different between gigabit and
100Mb/s speeds could be the difference between
the window staying open or the process going to
sleep.
