Re: Low capped TCP network speeds over the Internet

Thank you.

Just for completion sake, I tried both base sshd, and upstream
openssh-portable, both installed from pkgsrc and compiled. What I observed:

1. OpenSSH just needs a big recvspace for SCP transfers in general
2. NetBSD's sshd that comes in the base system with the HPN patch needs
HPN enabled to achieve good speeds. With HPN off (which is by default)
receive speeds are very low.
3. Upstream OpenSSH-portable (whether installed from security/openssh or
compiled from upstream) works fine without any modification (as long as
recvspace is big enough).

Not sure why it's that way but increasing the recvspace and enabling HPN
fixed things for me.

Thanks for your help and I hope this information helps others. Don't
hesitate to contact me directly if I missed something or got anything wrong.
