Actually, I do want to use this feature of pqact, but I don't think I
can afford the overhead of using LDM.

scp/sftp typically compress the data before encrypting it though the
default setting varies by platform/version. Over a slow connection
but using fast machines this can greatly increase transfer rates if
your data is compressible by a large amount. If the machine is slow
and the network fast, then the overhead of the compression can
actually slow things down. compression can be enabled/disabled by
command line options.
I forgot to mention in my original post that the data was already
compressed (gzipped tar file).
