How fast is compilation in general for you? I'm at ~3min to execute linkDebugFrameworkMacosX64 after changing one string, which slows down development quite a lot. Is that expected, should I buy a bigger machine or am I doing something wrong ?

[Dominaezzz]

I'm at about 20 seconds. I haven't seen up to 3 mins before though, is it a big project? Are you using cinterop?

[mbonnin]

It's this one: https://github.com/HearthSim/Arcane-Tracker/tree/master/kotlin-hslog. I don't think I'm using cinterop but there a few modules involved. Also the exported api might be a bit large as I didn't really look at optimizing it

[mbonnin]

compileKotlin takes maybe 30% of the time, the biggest contributor is the link task

[Dominaezzz]

I haven't built/linked a framework before, so I don't know if it's particularly slow, but I do know slowness is expected with Kotlin/Native builds rn.
Things should speed up by 1.4, by a lot.

[mbonnin]

The framework linking phase looks pretty intense. Linking a release framework sometimes takes up to 5min

[Kris Wong]

mine's high with 2 iOS targets

[mbonnin]

@Kris Wong do you mean it's taking you a long time as well ?

[Kris Wong]

yes

[Kris Wong]

I am guessing there's not much in terms of incremental processing

[Nick Halase]

oof, I’m at 8-10 minutes because I’m on a minimally specced Early 2015 MacBook Pro

[Kurt Renzo Acosta]

Mine runs up to 6 mins. 😢

[mbonnin]

Oh wow. Good to know I'm not alone in this... Looking forward to kotlin 1.4.

[Kurt Renzo Acosta]

On 1.3.70, we can export frameworks on a multi-module project. https://github.com/JetBrains/kotlin-native/issues/2423#issuecomment-550197856

This would make it faster.

[Dominaezzz]

Scary stuff. Waiting 8-10 minutes because you want to change some constant.

[mbonnin]

I'm looking into running gradle from a workstation stadia-like if it can bring it down to 4-5min it's already something... https://kotlinlang.slack.com/archives/C0B8H786P/p1578046777035300

I'm also seeing linking times of 3-5 minutes for a windows target

[Patrick]

Compiling usually only takes about 20% of the total time.

[Kris Wong]

I was able to speed up my assemble time by removing the compilation for iosArm64Test, as well as only building release frameworks

[Kris Wong]

that cut the number of target binaries in half

[Patrick]

What's the option to only build release binaries?

[Kris Wong]

targets.withType<KotlinNativeTarget> {
        binaries.framework(listOf(RELEASE))
    }

[sksk]

they don't care, every release it is becoming slower and slower https://github.com/JetBrains/kotlin-native/issues/733
they should have never shipped KN with such slow compile time, you see it with how low adoption is, i just can't understand why nobody else care

[sksk]

i am pretty sure it also affect JB productivity, this is why development and progress of KN is so slow, TDD must be a nightmare, even the compiler takes an eternity to compile

[sksk]

take a look at the year this issue was reported, 2017

[sksk]

KN could have been HUGE and so much more popular, the product manager have failed

[sksk]

and on top of that, they are silent, they don't even acknowledge how slow it is

[sksk]

JB have reputation of building slow software, and KN is no different.. that's gonna hurt them big in the future, can't wait to see their cloud IDE that requieres high VPS specs that it's gonna cost them a fortune to run

[mbonnin]

IntelliJ is sometimes slow but also best of its class in terms of features. I don't mind K/N beeing slow too much as long as it eventually settles to something reasonnable

[mbonnin]

Also because most of my code is MPP so I can test on the JVM without having to wait on K/N compilation each time. I can see how painful it would be to have to wait 5min each iteration 😕
