@spierce7 noticed you discussed about performance in https://github.com/Kotlin/kotlinx.serialization/issues/907
Wonder if you tried again with 1.9.0 (or dev builds), and what your approach has been since then.

[Edoardo Luppi]

With Kotlin 1.9.0

[Edoardo Luppi]

With Kotlin 1.3.72

[Edoardo Luppi]

With Kotlin 1.8.22

Well, seems we're heading to the right direction!
Thanks to the JS team thank you color

[Edoardo Luppi]

Latest dev build for 1.9.20 seems almost on-par with 1.9.0.
Maybe slightly higher numbers.

I've re-enabled back dynamic parsing (with Json.decodeFromDynamic), and you can shave off another 5 ms

@Edoardo Luppi you should try it again with es6 compilation in 1.9.0. It's a new option, and I noticed the JS it produces is much cleaner.

tasks.withType<KotlinJsCompile>().configureEach {
  kotlinOptions {
    moduleKind = "es"
    useEsClasses = true
  }
}

[Edoardo Luppi]

@spierce7 true, but the production code is the same, so no changes.
If the KotlinJS team keeps pushing to better performance, we should be good.
I'd say I'm good already at this point, at least for the MVP I'm building
