I don't know much about Python :-) but I see cnopts=pysftp.CnOpts() in the sftp.py script. This leads down the typical rabbit-hole of Google, grep, etc. and I find the pysftp project cookbook and added "cnopts.compression=True" in there. We'll see if it works - the cookbook says that compression is off by default.
So far (one cycle) it looks about the same - no errors, and "26 files, 34 seconds" versus the last uploads of 21 files, 32 seconds. (Second cycle - 21 files, 30.9 seconds. Faster, but tiny...) I may look into alternate providers, but I host this with Gandi (in Luxembourg) for $5/mo for a pre-configured and running host. As long as sftp works I'm happy to use it.
