KAPT: kaptKotlin Performance regression in Micronaut Core 4.2.0

[Spikhalskiy]

Actual Behaviour

kaptKotlin gradle building step with Micronaut Platform 4.2.0 takes 5x the time that it takes with Platform 4.1.6 on the same source code.

Version

Micronaut Platform 4.1.6 -> 4.2.0

@dstepanov I tried SNAPSHOT core with #10195 and while it may decrease the duration of kaptKotlin stage by 10%, it unfortunately doesn't compensate for 5x degradation that comes from the switch 4.1.x -> 4.2.x. The root cause is probably somewhere else. Let me know if you want me to upload updated sampling snapshots.

[dstepanov]

I think it was caused by https://github.com/micronaut-projects/micronaut-core/commit/e1a990bfe69672599f4fcc19dd1568d7387729d5 Do you have a lot of interfaces with annotations?

Can you benchmark using the async profiler? https://github.com/async-profiler/async-profiler: You can attach it to the Gradle worker remotely.

[Spikhalskiy]

@dstepanov I can't say so. We have some, but it's in low double digits. Nothing to justify a 30 seconds -> 2.5 minutes jump. Mostly it's controllers with data classes. I will take async-profiler snapshots of kapKotlin stage today.

[dstepanov]

Thanks, if you are willing, I might try to come up with a few branches for you to build locally and check if it does improve anything.

[Spikhalskiy]

@dstepanov Yes! I can build snapshots locally, give them a shot, and see if any of them bring the timings back. Whatever it takes. Currently, we are pretty much blocked from 4.2.x for developer productivity reasons.

[Spikhalskiy]

@dstepanov Unfortunately, #10237 seems to not help our project much.

kaptKotlin with Micronaut 4.1.6 is 30 seconds kaptKotlin with platform:4.3.0-SNAPSHOT + micronaut-core:4.3.0-SNAPSHOT is 2.5 mins

Let me know if you want an async-profiler recording updated for this PR.

[dstepanov]

Hmm, is it better than before?

Please try to profile

Make sure you use:

configurations.all {
  resolutionStrategy.eachDependency { details ->
    if (details.requested.group == 'io.micronaut') {
      details.useVersion "4.3.0-SNAPSHOT"
    }
  }
}

micronaut-core 4.3.0-20231211.112139-26 and 4.3.0-20231208.160954-24 give me the same time +- 2 sec.

Don't look like it's applied:

+--- io.micronaut:micronaut-inject-java:4.2.1
|    +--- org.slf4j:slf4j-api:2.0.9
|    \--- io.micronaut:micronaut-core-processor:4.2.1

Precessors need to change the version.

Have you tried to force it like I posted?

[graemerocher]

doesn't look like you have updated the dependency graph correctly

+--- io.micronaut:micronaut-inject-java:4.2.1
|    +--- org.slf4j:slf4j-api:2.0.9
|    \--- io.micronaut:micronaut-core-processor:4.2.1

Is still referenced, these need to refer to the 4.3 snapshot

[Spikhalskiy]

Thanks, let me pin micronaut-core-processor version to SNAPSHOT and I will post an update

[Spikhalskiy]

That was it. kaptKotlin timing is great on the 4.3.0-SNAPSHOT. 4.3.0-SNAPSHOT: 15 sec 4.2.1: 3 min 4.1.6: 30 sec This is awesome!

[dstepanov]

Perfect! Can you try KSP? 4.1 vs 4.3?

[Spikhalskiy]

Unfortunately, we can't fully build our project with KSP because of https://github.com/micronaut-projects/micronaut-core/issues/9764 I did post an update on 4.2.1 release here though (on the part of KSP build that I can observe): https://github.com/micronaut-projects/micronaut-core/issues/9750

[dstepanov]

Ok, it should be faster, too. I am closing this one.
