Is Jetpack a Good Tool to Optimize Performance?

There will just be one baseline profile per APK that profile will be generated based on the rules that were packaged with each library that you depend. We did use macro benchmarks to add a lot of baseline profiles to import the libraries like recycler view, like constraint layout and we did see huge difference in performance. And those are all informed by using the macro benchmark library. It's not just for startup, it's also for Jank. That's important to think about.
