Xcode profiler on iOS Simulator, 5s wall time 😅
I need at least move that off the main thread.

[Sam]

Wall time?

[Marc Knaup]

over the period of 5s in the real world I had 224ms main thread work just for KotlinInt boxing

[Sam]

Is this in Kotlin Native, Android project or the back end? Kinda curious too if it all is coming from one call site or that's just something happening throughout the project.

MPM project - iOS Simulator - Xcode profiler
but I think it's kotlinx.serialization at work here

[Marc Knaup]

Unfortunately the profile doesn't seem to be able to show me any call sites

[sandwwraith]

kotlinx.serialization shouldn't box anything, unless you have Int in some generic position (i.e. Box<Int>). But such boxes usually degrade performance everywhere

[Marc Knaup]

hmm no, I don't have something like that
