Bug Description
This is a wishlist item: hpn-ssh would be a big data-transfer speed improvement for many Ubuntu users, particularly scientific organizations like universities and observatories that transfer large amounts of data over long-haul networks, and large commercial users. hpn-ssh is a patch on openssh that just makes the TCP window variable in length, overcoming a static (and too-small) window size that is in openssh. No modifications are made to the security aspects of the code. Measured transfer rates are improved over some nets by a factor of 20. It's in wide use already by banks, the US government, many grid computing centers, and security companies. Even if it's not patched into openssh, making an alternative version available would be a service to the community. Other distros have this, but synaptic shows me nothing for Ubuntu. Here are some sites:

Why is this patch not included upstream? Because of the no-encryption
part with has "issues"?
