After testing a little, I noticed a very strange behavior. > buf := make([]byte, 30000000) > times := time.Now() > nc.Publish("test", buf) > log.Println(times.Sub(time.Now())) 801ns > buf := make([]byte, 3000000)...

> for { > buf := make([]byte, 3000000) > times := time.Now() > nc.Publish("test", buf) > log.Println(times.Sub(time.Now())) > time.Sleep(100 * time.Millisecond) > } 2019/09/12 02:52:54 -856ns 2019/09/12 02:52:54 -846ns 2019/09/12...

go version go1.12.9 darwin/amd64 ``` package main import ( "log" "time" nats "github.com/nats-io/nats.go" ) func main() { var urls = "any" opts := []nats.Option{nats.Name("any"), nats.Token("any")} nc, err := nats.Connect(urls, opts...)...

time.Since(startTime) same speed result > 2019/09/12 03:04:20 9.862577ms > 2019/09/12 03:04:20 9.725442ms > 2019/09/12 03:04:20 8.069759ms > 2019/09/12 03:04:20 7.675831ms > 2019/09/12 03:04:20 7.815554ms > 2019/09/12 03:04:20 7.33363ms > 2019/09/12...

only bug 300000 size not 30000 not 3000000 it is very strange for me to see.
