The major parts of the source code involved when retrieving these files are
*identical* for both protocols. The HTTP code has some initial headers and
the FTP has an initial command-response phase, but the the actual file is so
terribly huge and both protocols are downloaded using the *exact* same code
sequence.

Have you performed any other measurements using other tools on these
platforms? Can't it just be the fact that IIS serves FTP files a lot worse?

Can you try to use the Linux version to fetch the HTTP and FTP files off the
IIS server and see if you can see any speed difference? I mean when used on
the local network.
