I was skeptical of the claim that it's faster than traditional SSH, but the README specifies that it is faster at establishing a connection, and that active connections are the same speed. That makes a lot of sense and seems like a reasonable claim to make.

SSH is actually really slow on high latency high bandwidth links (this is what HPN-SSH patches fix: https://www.psc.edu/hpn-ssh-home/hpn-ssh-faq). It's very apparent if you try running rsync between two datacenters on different contients.

HTTP/3 (and hopefully this project) does not have this problem.

Sounds like a complex change to fix a security protocol but, reading the page, it seems to just increase the send buffer, which indeed makes sense for high-latency links
