Re: Do NTL shape FTP traffic? Can't get anywhere near my connection speed

With FTP traffic (irrespective of port number), the RWIN matters a great deal more, and given that the connection is international, I do indeed think that the poster should try increasing their RWIN for long-haul FTP downloads.

To imporve FTP uploads, it is the server's RWIN that needs to be increased.
That is correct rwin directly affects ftp transfer's much more then http and in particular when proxies are used.
