Perfetto

Perfetto is an open-source performance instrumentation and tracing toolkit developed by Google that enables developers, system integrators, and performance engineers to collect, visualize, and analyze detailed runtime metrics across Android, Linux, and Chrome platforms. Designed to replace the legacy Systrace workflow, the tool captures kernel-level ftrace events, userspace annotations, hardware counter data, and high-frequency process statistics, then presents them in a unified web-based trace viewer that supports multi-gigabyte traces with sub-microsecond resolution. Typical use cases include diagnosing UI jank in Android applications, measuring scheduler latency on embedded Linux devices, profiling Chrome renderer processes for memory bloat, and correlating power-rail data with CPU frequency changes to optimize battery life. The project ships monthly stable releases; version 54.0, published in May 2024, introduces configurable binary probe filtering, improved SQL-based metrics calculation, and a compact trace format that reduces file size by up to 35 % compared with earlier 53.x branches. Eight major revisions have appeared since the 2020 debut, each adding platform-specific data sources such as Android’s GPU timing packets, Linux eBPF-based network tracking, and Chrome’s JavaScript heap snapshots. The software is classified under Developer Tools / Debugging & Performance Analysis and is distributed under the Apache 2.0 license, allowing commercial and private modification. Perfetto is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
