Does anyone know of any benchmarks of Kotlin/native vs other more mature equivalent languages (Swift, rust, C++, etc)? I'm interested to know where Kotlin is in it's performance process. I've seen this ( https://github.com/msink/kotlin-pi ), but its just algorithms, without much / any ARC, or OO.

Yes, kotlin-pi tests only algorithm - performance is almost x1. On the other hand - https://github.com/frol/completely-unscientific-benchmarks tests memory management - performance is x36 times slower to etalon, only CPython is worse - x74. For real applications it will be somewhere in between (x1 - x36)

this ^^^ benchmark is not so interesting, IMO, so my suggestion would be to create a test similar to your expected workload, and report results/problems to us

Sure that benchmark is extremal case for heavy use of memory management, in real workloads result is not so bad. But result for Swift is x10, and for Kotlin/JVM - x3.

I'd expect Kotlin/native to be similar to Swift after Kotlin/native is optimized once all is said and done since their memory management strategies are similar. Is there any reason that shouldn't be the case @olonho?
