Larger stack traces also does something in Scala. So you need realistic use cases to compare nicely. Our big comparison was a billion record processing system that was in Scala, then converted to Kotlin line-by-line just syntax cleanup. 16% faster over 4 hour run. It was mostly due to the collection conversions. (had we known that, we might have written Scala to prevent them, some use of libraries would not allow that though)
