Announcing QCP
I'm pleased to announce the first release of qcp.
The QUIC Copier (qcp) is an experimental high-performance remote file copy utility for long-distance internet connections with the following features:
- 🔧 Drop-in replacement for
scp - 🛡️ Similar security to
scp, using existing, well-known mechanisms - 🚀 Better throughput on congested networks
qcp exists because I needed to copy multiple large (3+ GB) files from a server in Europe to my home in New Zealand.
I’ve got nothing against ssh or scp. They’re brilliant. I’ve been using them since the 1990s. However they run on top of TCP, which does not perform very well when the network is congested. With a fast fibre internet connection, a long round-trip time and noticeable packet loss, I was right in the sour spot. TCP did its thing and slowed down, but when the congestion cleared it was very slow to get back up to speed.
If you're interested you can find qcp here:
