I'd tunnel the port your use for iperf (ssh -L 5001:localhost:5001 cyndane) and run the same test as you initially did (iperf -c localhost). I expect that you'll see a value that's larger than the 35-45 Mbps you get for rsync+ssh, meaning that rsync is the bottleneck. And most of the time, that makes sense, because it's often doing other things than transferring data.
