09/17/2020, 6:33 PM@e5l will performance of native ktor-io will be improved sometime in near future ? Now it's ~ 10 times slower than on jvm
Or do you know, is it related to slow native runtime, or because of heavy atomics usage on native, or smth else?

benchmark: https://github.com/rsocket/rsocket-kotlin/blob/ktor-io-benchmarks/benchmarks-io/src/commonMain/kotlin/Frames.kt
Raw results:
JVM vs JS - writing is 2-3 times slower on JS, reading is 5-6 times slower on JS
JVM vs Native(Release) - writing is 40+ times slower on Native, reading is 100+ times slower on Native
