\S{faq-psftp-slow}{Question} PSFTP transfers files much slower than PSCP.
We believe this is because the SFTP and SSH2 protocols are less
efficient at bulk data transfer than SCP and SSH1, because every
block of data transferred requires an acknowledgment from the far
end. It would in theory be possible to queue several blocks of data
to get round this speed problem, but as yet we haven't done the
coding. If you really want this fixed, feel free to offer to help.
The throughput of PSFTP 0.54 should be much better than 0.53b and
prior; we've added code to the SFTP backend to queue several blocks
of data rather than waiting for an acknowledgement for each. (The
SCP backend did not suffer from this performance issue because SCP
is a much simpler protocol.)
\S{faq-bce}{Question} When I run full-colour applications, I see
areas of black space where colour ought to be.
