I had also been looking at HPN SSH. If you try that you should increase the
buffersize as well: https://github.com/rapier1/openssh-portable/pull/11

There is an open issue with AES-CTR in HPN SSH:
https://github.com/rapier1/openssh-portable/issues/13#issuecomment-279778429

I did not run any tests yet. I will see if I can build it for Windows under
Cygwin. https://github.com/rapier1/hpn-ssh/tree/master/contrib/cygwin
