在Go中使用渠道是否对性能有利？

Question

I'm wondering as to whether channels are efficient enough to be used as part of coding a Go program.

Answer 1

Generally speaking, yes, channels are fast but we can't tell if you should use it without knowing your program. I'd say this part isn't constructive.

As for the implementation, it's available when you install Go with the sources. Look for exemple at src/pkg/runtime/chan.c.

Most Go concurrent programs rely on channels. If you want to code in Go and execute concurrent tasks, I'd say you have almost no choice : use channels, profile, and see if you have a problem related to channels.
