[libssh2] High Performance SSH/SCP - HPN-SSH

"SCP and the underlying SSH2 protocol implementation in OpenSSH is network
performance limited by statically defined internal flow control buffers. These
buffers often end up acting as a bottleneck for network throughput of SCP,
especially on long and high bandwith network links."

Should be an interesting read even for libssh2 hackers =>
