I discovered some useful info while working on an FTP slowness complaint
(~160K over a full T3) Windows' TCP stack implementations are detuned by
default. Win 9x's sucks. Win 2K & ME are better at window adjustment but by
default use an MTU of 570 when xmiting to another subnet. Lots of other
options/registry keys. See:

Thought this might be usefull to many.
