--- Comment #2 from Scott Baker <scott at perturb.org> ---
I came here to request alternate compression methods, and found someone
had beat me to it. Consider this my +1

Currently OpenSSH only supports GZIP compression which has speed
constraints on modern CPUs. Enabling compression on file transfers over
a gigabit link actually increases the amount of time taken to transfer
large files due to the limitations of GZIP.

Please consider adding support for alternate compression methods. LZ4
and ZSTD would be excellent choices.

Even better would be support for external compression methods like
`tar` does with `-I`. That way in the future if new/better compression
algorithms are found SSH will automatically be able to utilize them.
