I need to ramp up quickly  on idiomatic Kotlin patterns using coroutines with both blocking and non-blocking I/O.  Does anyone have any substantial experience in this area?  In particular,  I will like to know how suspend fuctions with blocking network I/O performs against non-suspend functions using NIO.

<https://github.com/Kotlin/kotlinx.coroutines/blob/master/coroutines-guide.md>

this document is your goldmine. It will provide you with the concepts to handle blocking or nonblocking I/O. I'm not aware of any resources specifically for the use case but the concepts will be the same

There's a kotlinx.coroutines artifact for nio

<@U9UKZTV7V> and <@U3ZLHBTLG> Thank you for your responses.  I looked at the Kotlin artifact for nio before and did not think it was rich as I expected.  Maybe I was too quick in my judgement and will take a look again. Thanks for the pointer <https://github.com/Kotlin/kotlinx.coroutines/blob/master/coroutines-guide.md>.   I will also look at this again.

<@U6Z3T996C> `nio` is pretty large, are you dealing with files? protocol specific sockets? rest-ful port-80 business?

<@U0ZFBBUBU> All the above.  I am writing a streaming product.  To scale and perform all its component should be asynchronous and/or non-blocking.

Kotlin's suspend coroutines with blocking I/O is tempting from an ease of use perspective but I wonder about performance.  Do you know if anyone has benchmarked the two approaches?
