@liliang8858, this library creates itself only two internal goroutines. It seems there are many goroutines using WriteRecord in the test app. How many?

There is a main goroutine sending data to a server using a single connection. If this goroutine does not manage to send data quickly other routines must wait. You have to balance the number of writing goroutines.

You can use multiple clients to write using multiple connections.
