threading model

[Infixz]

is that hysteria using 3 threads as default? i noticed it will spawn more thread when one thread blocked due to network, but will it kill the dead thread or kill the spawn'ed thread after previous one resumed?

It spawns 2 goroutines per client connection, but goroutines are not mapped 1-1 to system threads. You can read more about how goroutines are scheduled here: https://betterprogramming.pub/deep-dive-into-concurrency-of-go-93002344d37b
