netlimit is a small package that allows you to control bandwitdh usage of net.Listener and net.Conn, it delivers custom wrapper types around net.Listener and net.Conn interfaces and util functions like netlimit.Listen() and netlimit.ListenCtx() to bootstrap the whole process
Create netlimit.Listener
//globalLimit limits bandwidth of a listener
globalLimit := 1024 //Bps
//localLimit limits bandwidth of a single connection
localLimit := 512 //Bps
ln, err := netlisten.Listen(proto, addr, globalLimit, localLimit)
Use it as you would any other net.Listener e.g
http.Serve(ln, handler)
You can tweak limits during runtime
Change local(per connection) limit use
err := ln.SetLocalLimit(newLocalLimit)
Change global(server) limit use
err := ln.SetGlobalLimit(newLocalLimit)
