Description
During the 2024 GNOME STF grant, I used the Tracy profiler to investigate performance in Mutter and GNOME Shell, finding several real issues, many now fixed. In this talk, I’ll use some of those investigations to show you what Tracy can do: timeline view, statistics, plots, call stacks, memory profiling, and even profiling over LAN. I’ll show how you can integrate Tracy to your app or library written in C, C++ or Rust, so you can diagnose performance problems and get a better understanding of where your code spends time and memory.
