Looking for help in sizing `-Xmx`  of the Kotlin daemon in my project.

I see that a big chunk of compilation is being done in  `org.jetbrains.kotlin.gradle.*`  tasks. (all these tasks run in the daemon, right?)

Contrary to my expectations, my builds are performing well (minimal GC time) with low `-Xmx` like `-Xmx=1536m`  for Kotlin daemon and `-Xmx=5g` for Gradle daemon.

I'm using the default compilation strategy where in Kotlin daemon runs as a separate process

What can explain this?

BTW, I tried flipping the ratio, i.e. lower Xmx for Gradle and higher Xmx for Kotlin (like 4g for Kotlin and 2.5g for Gradle) - it resulted in OOMs.

yes, `KotlinCompile` and `KaptGenerateStubsTask` should use Kotlin daemon.  You could attach VisualVM (or other tool) to the KotlinDaemon process and inspect there heap usage

Tried VisualVm. `KotlinCompile` and `KaptGenerateStubsTask` do take up significant CPU but not so much with respect to memory
