In May 2017 Allan Jude posted a new HPN patch here: https://lists.freebsd.org/pipermail/freebsd-current/2017-May/066015.html Quote: > In my benchmarks with 100ms of latency (from dummynet) is increases SSH > send throughput from 1 megabyte/sec to 225 megabytes/sec provided a > large enough socket buffer. I cannot reproduce that. I applied a modified version of this patch to OpenSSH-portable for Windows: https://github.com/Jan-E/openssh-portable/commit/e5c711f66aa3a14980dc7e0ca8504d0bda614fa6 For anyone that wants to try it: https://phpdev.toolsforresearch.com/expect.7z The scripting is done with Expect for Windows: https://github.com/zetamatta/expect/issues/8#issuecomment-416445736 -- Jan ------------------------------------------------------------------- Unsubscribe: https://cool.haxx.se/list/listinfo/curl-library Etiquette: https://curl.haxx.se/mail/etiquette.html
