O que é um arquivo PERFETTO-TRACE?

Mais informações
System tracing allows Android users and developers to record information about their device's activity and performance. Developers can use this information to review, troubleshoot, and optimize an application's performance. For example, a developer may discover that their app's CPU usage is too intensive, thanks to the information recorded in a system trace.
Android 10 and later versions use a system tracing tool called Perfetto to perform and record traces. Traces saved using Perfetto-based tools, such as the Android Studio CPU profiler, System tracing utility, and Perfetto command-line tool, are saved as PERFETTO-TRACE files.
