Just as side information: In local copies all files are copied wholly,
the diff algorithm is not in effect. So if a file changes then it still is
copied completely (without --partial, --no-whole-file etc).

Second thing: From what I remember rsync does a lot of stat calls to
get every file's properties. This is more expensive on cygwin/Windows
than on linux directly. Rsync also uses processes/threads which are
easier/faster to create and switched to on linux than on Windows.

A Windows native implementation of rsync could run faster than the
original rsync with cygwin layer. Some time ago somebody announced
a new program using the rsync algorithm. But I never used it so I don't
know about the features or speed.
