Hi all! I have a Ktor server with a Netty engine. On requests, I just call 
delay
for some time (say 20 seconds) and then respond with a string. I thought that when I call 
delay
, I can serve other requests while previous requests are suspended, but instead, I have to wait until those requests are done and only then I'm able to serve new requests. How can I serve new requests when my previous requests are suspended? I thought it works like that by default, but now I really don't understand.

It does work by default. The problem likely lies elsewhere in the server or the client. You need to share more about your setup to get to the root of this.

Are you calling delay in the middle of a DB transaction so you are blocking accessing to some data in the next call? Just a clue…

Copy code
fun main() {
    val req = AtomicInteger(0)
    embeddedServer(Netty, port = 8081, host = "127.0.0.1") {
        routing {
            static("/static") {
                resources()
            }
            get("/wait/{waitMillis}") {
                val r = req.incrementAndGet()
                log.debug("Got request $r")
                val waitMillis = call.parameters["waitMillis"]!!.toLong()
                delay(waitMillis)
                call.respondText("Hello, i've waited for ${waitMillis}ms")
                log.debug("Sent request $r")
            }
        }
    }.start(wait = true)
}

And the client?

Here is the code of a test application. When I do a lot of requests, I expect it to finish in 
waitMillis
ms, but it processes requests almost one-by-one
just a browser requests in new tabs

Try curl, maybe the browser waits for each

Really, it was a browser issue. Thank you!
