Hysteria2 Performance Tuning: Bandwidth Configuration, Congestion Control, and Multiplexing in Practice
Hysteria2 is based on the QUIC protocol (UDP), and is theoretically much faster than TCP-based protocols in high-latency, high-packet-loss networks. However, many people find speeds are mediocre after deployment—usually because bandwidth parameters aren’t configured correctly or the right congestion control algorithm isn’t selected. This article focuses on tuning. It assumes you’ve already got the basic deployment working (see Hysteria2 Setup Guide) and now want to maximize your speeds. ...
