I've found rsync to be painfully slow on large folders -- hours to sync thousands of files, even

I've been told (on this list) that how you mount the Windows drive in Cygwin
matters.
I use this in my /etc/fstab:
d:/ /cygdrive/d ntfs binary,posix=0,user,auto,notexec 0 0
Unfortunately, it's still not as quick as I think it ought to be.
(If someone out there can recommend better settings, I'm open!)
I regularly rsync a collection of hundreds of files, each about 2Gb in size.
Windows describes the partition as an NTFS Basic Data Partition. It takes
rsync a long time to get started (i.e., to figure out which files need
transferring).
My rsync uses these flags:
rsync -avuP --partial --partial-dir=.rsync-partial --log-file=...
--log-file-format=...
These flags seems to give speedy directory scanning:
rsync -r --chmod=D2700,F600 -t -z -p -v --size-only --partial-dir=.rsync-partial
