Perfetto
A next-generation system-level tracing platform led by Google. It comprises an on-device daemon, data sources, and cross-platform tools for parsing and visualizing traces, and it defines the open Trace Protocol Buffer format.
Timeline (last 90 days)
A Perfetto trace records the work of the main thread, render thread, and GPU on the device; for Compose developers the main thread deserves the most attention, because composition work mainly happens there.
Android XR apps need to focus on performance, rendering and stability; apps built with the Jetpack XR SDK can use Perfetto for performance profiling to confirm they meet the minimum frame rate requirements.
Perfetto defines an open Trace Protocol Buffer format, and the official Tracing 2.0 sink outputs a Perfetto-compatible format, allowing app traces to be viewed against system traces on the same timeline.
