Delay in building the project in dev mode

[geissondaSilva]

I am migrating a legacy project that used thorntail as a framework.
We recently decided to migrate to quarkus to have better performance in production and development.
After the project configuration stage using only dependencies compatible with quarkus, we identified a construction time greater than that of thorntail. When analyzing the problem and performing profiling in the construction phase, we identified that a build stage was analyzing the project's beans to assemble the data for the quarkus devui page.

Class: io.quarkus.arc.deployment.devconsole.ArcDevConsoleProcessor.java
Quarkus version: 2.16.9-Final

The addNodesDependencies function of the ArcDevConsoleProcessor class was the one that spent the longest time running when starting the application (around 70% of the time consuming CPU)

We understand that the best way would be to break this project into several others. However, due to the urgency, we need to keep everything in one project only due to the high refactoring time.

My question is how can I disable this functionality to save build time in development mode in my project?

any chance you can try newer quarkus version? quarkus 3.4+ would potentially not have this calculation.

@geissondaSilva https://github.com/quarkusio/quarkus/blob/main/CONTRIBUTING.md#checking-an-issue-is-fixed-in-main can help with that.

@mkouba I performed the local test and had a great result. my build time dropped from 5 minutes to 30 seconds.

Thanks a lot for the help. I thank the entire team.

Ok, I will send a PR for the 2.6 branch and a separate one for the main branch. And maybe one for the 3.2 branch.

@gsmet Does it make sense? I mean it's a bit confusing since we're adding a config property that will be present in 2.6 but not in 3.0 etc.

[geissondaSilva]

@mkouba Is there any forecast for the release of the correction version?

[maxandersen]

@geissondaSilva just to set expectations. 2.x is not on a regular release schedule so not in any active plans.

If this is urgent for you please use @mkoubas branch to build your own or if you have a red hat support you can open bug against red hat build of quarkus 2.13.
