Option to specify TCP window size, similar to the -w: argument in the bundled WindowsXP ftp.exe:

Specifies the size of the transfer buffer. The default window size is 4096 bytes.

This option allows much faster FTP transmissions over high-latency WAN links - up to 600% speed improvement.

A default window size of 64 Kbytes is recommended, as per RFC1323. See also

This may also be implemented in FileZilla Server.
