I creted a ~250MB test file and was able to scp it between these NASes
at ~40mb/s
rsync still was transferring at about 12 mb/s over a direct 1Gb/s link.

I am dealing with a lot of small files... about 50 GB of ~180,000
someodd files.
I'll check out that -W, but is there anything else that might improve
this seemingly-pathetic performance?

While 12mb/s does seem rather slow, your problem is likely a
combination of cygwin and the slower machine. Cygwin is, well, slower
than just running on a standard Unix/Linux platform and running it on
a slower machine will cripple the transfer even more. I would suggest
taking SSH out of the equation and setup a rsync daemon; perhaps that
will speed things up.
Otherwise, if you look at the time savings rsync has given you, one
might not complain as much. If you had transferred the 58GB using
straight scp, it would have taken ~3.3 hours, rsync did the same job
(net result, anyway) in 30 minutes. That is very impressive.
