I ran an rsync test using the RDC program that comes with the Server 2008 SDK. The RDC program is a simple program to demonstrate Microsoft's Remote Differential Compression algorithm. It uses the API for RDC to copy a file across a WAN/LAN connection. The program, as-is, has little functionality and a lot of limitations but I thought it might be fun to test. I compiled the RDC code as-is using Visual Studio 2008.
A run on an 80GB file took approximately 14.75 hours to transfer the file across a gigabit LAN. The same run using rsync 3.0.3 took 1.62 hours. The rsync run used cygwin for both the client and server with the preallocate patch applied. I'm not sure this is a fair comparison given the rudimentary application used for RDC but it sure looks like rsync blows away RDC.
