I've been using rsync, unison and similar tools on Windows and Linux since basically forever. In my humble opinion, the problem is the Windows file system 
performance, not the synchronization tools. As a separate example, try to download the boost source code, and extract the archive. I can do the extraction in 
way under a minute on Linux, but have to wait many many minutes on a similarly equipped Windows machine.

Just my two cents.
