Using BBR in the server configuration file significantly increases upstream traffic.

Tried Cubic, but it was very slow. The new_reno backend wouldn't start up. BBR is fast, but under asymmetric upload/download traffic, downloads hit 1T while uploads only reached about 1.4T.

This is characteristics of BBR.

@Itsusinn I used to think it was a QUIC feature too, but when I tested Hysertia2's BBR, the difference wasn't that significant—only about 70GB on 1TB. It might be because the two proxies use different BBR methods.

I anticipate that the upstream project Quinn will merge support for the BBR3 algorithm. It is possible to reduce retransmissions while maintaining throughput.

@Itsusinn 好的 如果出新版我会测试好并把数据发给你

@sunyuchen-max I'm quite interested in BBR3. I can modify a version based on the unmerged BBRv3 branch for your testing.

I shall provide you with this information as soon as possible.
Additionally, I would appreciate details regarding the changes in throughput.

@sunyuchen-max tuic-Bbrv3 Releases

[Itsusinn]

I add BBR3 in 1.7.0

Welcome to try it out 😁

[Itsusinn]

I am going to add a feature allow configure congestion control based on user, anyone wants this feature?

Looks like

user1: bbr
user2: bbr3

@Itsusinn 测试了下流量上行还是比以前高很多 下行跑1T 上行1.3T 但是bbrv3 好像非常消耗cpu 之前跑200m/s我机器cpu才满 现在跑120m/s cpu就炸了

[sunyuchen-max]

@Itsusinn 是acl问题 当使用acl分流的时候cpu就炸了 我把acl域名删了 cpu 就正常了
