but a couple of months ago a link appeared here describing a HPN (as in hihg performance enabled) ssh patch. i kept that mail for a very long time because i was very much interested in the answers of the ssh developers, but there was none. and so i assumed it must be rubish or something.
It's not, but there's not much we can tell you that isn't on the PSC site. In fact, most of my reply is going to be telling you things from their site. The shortest way to say it is: you're barking up the wrong tree.
HPN-SSH improves OpenSSH performance in situations that you and I don't deal with. Maybe I'm mistaken... do you have an OC-3 connection you're trying to scp files across? If you are dealing with T-1s and 100Mbps LANs (and maybe Gigabit LANs, I'm not sure), then HPN-SSH doesn't matter to you.
It's unfortunate that the patch has not yet been incorporated, but if *you* want faster performance for *your* servers, use faster processors and crypto accelerators, because that's what makes SSH slow for *you*.
