Perfetto is a production-grade open-source stack for performance
instrumentation and trace analysis. It offers services and libraries and for
recording system-level and app-level traces, native plus Java heap profiling, a
library for analyzing traces using SQL and a web-based UI to visualize and
explore multi-GB traces.}
