@cbruegg @vonox7 E.g, if you code invokes Thread.sleep(1000) which blocks a thread for 1 second, then no amount of wrapping it into async will let you handle 100k of such operations simultaneously. However, with delay(1000) (non-blocking, but suspending) it is a nobrainer. You are welcome to perform an experiment from here yourself to verify it: https://github.com/Kotlin/kotlinx.coroutines/blob/master/coroutines-guide.md#coroutines-are-light-weight I really recommend trying both the async version and the one where you replace launch(CommonPool) {...} with thread {...} and delay with Thread.sleep.
