As a Chinese user who regularly breaches the GFW, QUIC is a god send. Tunneling traffic over a QUIC instead of TLS to breach the GFW has much lower latency and higher throughput (if you change the congestion control). In addition, for those foreign websites not blocked by GFW, the latency difference between QUIC and TCP based protocol is also visible to the naked eye, as the RTT from China to the rest of the world is often high.

- svara 3y agoWhat do you need to change for congestion control?
- bdd8f1df777b 3y agoThe default congestion control is CUBIC, which is very slow for connections between China and the rest of the world. Google's BBR is a great improvement, and sometimes I use "brutal" congestion control, which is basically a constant speed.
- girishso 3y agoAny specific tool you can recommend?
- bdd8f1df777b 3y agohysteria and tuic. Both are based on QUIC. But you need a server outside China though.
- apatheticonion 3y agoI want to visit China but am afraid I will not be able to breach the GFW (as other friends have not been able to). Any resources you can point me to to help me be more successful?
- gamepsys 3y agoYou won't casually breach the GFW. I would treat any advice posted publicly on the internet about how to breach the GFW as probably-malicious. They are better at networking than you are.
- qingdao99 3y agoYou will casually breach the GFW if the VPN you pay for is not blocked yet.
- hker 3y agoBeware when using VPN to breach the GFW. Recently a Chinese netizen had to pay over 1 million yuan (>145K USD) for using VPN [1][2]. Before this incident, only VPN service sellers were prosecuted [3]. Beware when doing this casually.
