go - why is fasthttp like single process?

Question

requestHandler := func(ctx *fasthttp.RequestCtx) {

    time.Sleep(time.Second*time.Duration(10))
    fmt.Fprintf(ctx, "Hello, world! Requested path is %q", ctx.Path())
}


s := &fasthttp.Server{
Handler: requestHandler
}

if err := s.ListenAndServe("127.0.0.1:82"); err != nil {
log.Fatalf("error in ListenAndServe: %s", err)
}

multiple request,and it cost time like X*10s. fasthttp is single process?

after two days... I am sorry for this question,i describe my question not well.My question is caused by the browser，the browser request the same url by synchronization, and it mislead me, it make think the fasthttp web server hanlde the request by synchronization.
