Over the last years, there were several issues in the SCP protocol,

the voices there said that they use SCP mostly for simple ad-hoc copy and
because sftp utility does not provide simple interface to copy one or couple
of files back and forth and because of people are just used to write scp
rather than sftp.
Some months ago, I wrote a patch  for scp to use SFTP internally (with
possibility to change it back using -M scp) and ran it through some
successful testing. The general feedback from upstream was also quite
positive so I would like to hear also opinions from our users.
Has that testing included performance measurements, both on high bandwidth
low-latency transfers and low bandwidth high-latency transfers?
At least in the past SFTP used to be worse than SCP on high-latency
