How to benchmark a Kotlin Program?

Question

Are there any tools available the can help benchmark some code in Kotlin?

I can use something similar to the approaches suggested here: http://www.ibm.com/developerworks

Answer 1

All low level benchmarking tools are the same that you would use for Java, since the byte-code is identical.

If by "Kotlin native tools" you mean syntactic sugar for measuring (relative) performance, then stdlib provides measureTimeMillis and measureNanoTime:

fun main(args: Array) {
    val benchmark = measureNanoTime {
        // some slow code here
    }
}

The results may vary from run to run for obvious reasons, but it may help to estimate relative performance.
