I had the same issue with backups running slowly over rsync from windows
hosts. The problem started after I upgraded cygwin to 1.7 in order to
support long file names. On each workstation I'd been getting 80%
utilization of a 100Mbit network card. After cygwin 1.7 I was only getting
8%.

I compiled a newer version of 1.7 and its back up to 80%. Or you can try 1.5
to see if that's your issue without going through the trouble of compiling
your own... but no more long file names of course.

I just gave this a shot, and although it was slightly faster, it was not
significant enough to fall outside a margin of error (about two minutes
faster on a 40 minute backup.)

If I were to speculate about a "culprit" for rsync's poor performance
relevant to smb, I'd suggest that it's the many layers sitting between
rsync and the Windows' file API.
