tar -c | nc on the AIX side and then nc | tar -x on the Windows side.
You'll of course need to find a version of netcat and tar for Windows.

This should be significantly faster than SSH although there is no
encryption or authentication.

You may also want to mount -noatime on the filesystem, if AIX supports
such a thing, as writing an updated entry when the file is copied isn't
exactly useful for you.
