What is the license of these patches? There doesn’t seem to be anything on the website, nor in all of the patches available for download.

Are there other reasons apart from licensing why this has not been merged into mainline OpenSSH?

Edit: At least the multithreaded AES-CTR cipher has license information in the header, which seems to be standard BSD. It stands to reason that the rest of the patches have the same license?

The Sourceforge page says the project is BSD-licensed. But if the license isn't applied to all the files, and no other root-directory file says that all the files contained within are licensed as such, i'm pretty sure you're not legally covered. If I were a distro I wouldn't include these without asking the authors to put a license declaration covering all the patch changes at the beginning of the file.

I'm not sure about that.

I think that it was merged into FreeBSD a while back though: http://svnweb.freebsd.org/base?view=revision&revision=224638

ESNet has a good website for high-performance data transfers: http://fasterdata.es.net

In addition to host and network tuning guides they also have a list of data transfer tools, including HPN-patched sftp and scp, but they recommend GridFTP because it supports parallel streams: http://fasterdata.es.net/data-transfer-tools/gridftp/
