Yep, however by default windows uses sliding window size. (auto adjusted by os.. not sure, if some of these 'tweaks' disable it - if it's disabled at either end, os is forced to use default window size)

MSDN says those tcpwindowsize settings gives the max window size. windows starts slowly and increase if needed until this maximum is reached.
By default, those settings aren't in the registry, and are then defaulted to 16kB.
The farther you're trying to send, the larger the window should be. The bigger your internet connection, the bigger window size you'll need. Thus the formula that was pasted 12,000 times in this thread.
Your ftp server will keep throtling itself, waiting for acks from the remote server, if the window size is too small.

If uploading (maybe downloading sometimes too) is slow on a win2k3 server, then you should fix the settings of "file and printer sharing for microsoft networks" under properties of your local area connection.. or similar. Worked 4 me.
