Are there any benchmarks comparing https://github.com/Kotlin/kotlinx.collections.immutable to JVM alternatives (Capsule, Paguro, Bifurcan)?

This is not part of the stdlib so you can ask on their issue tracker perhaps

they have benchmarks in their repo https://github.com/Kotlin/kotlinx.collections.immutable/tree/master/benchmarks

I've seen those, but I was hoping for a web page comparing kotlinx.collections.immutable to other libraries. Something like this: https://github.com/lacuna/bifurcan/blob/master/doc/comparison.md#hash-maps
