I entirely agree that multiple connections shouldn't actually be necessary for speed, but they help in multiple situations (long-distance transfers, same DC between servers, NFS), and it's not just about amortizing per-file setup overhead.
There is some info on the optimizations in the docs, but I agree that a more complete technical explanation of all the things syq does could be useful. I will work on one. On the other hand, I also tried hard to make it just go fast without needing the user to understand why it is fast or tune anything. For instance, the number of connections is auto-tuned by default.
