In this talk, he uses some of those investigations to show what Tracy can do: timeline view, statistics, plots, call stacks, memory profiling, and even profiling over LAN. He shows 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. Ivan Molodetskikh is a long-time contributor to various open-source projects. His GNOME work includes improving input latency and performance in Mutter, the overhauled screenshot UI shipped in GNOME 42, and two Circle apps, Identity and Video Trimmer. Currently, Ivan is pursuing a PhD in computer vision, and making niri, a scrollable-tiling Wayland compositor. GNOME is a free and open-source software environment project supported by a non-profit foundation. Together, the community of contributors and the Foundation create a computing platform and software ecosystem, composed entirely of free software, that is designed to be elegant, efficient, and easy to use. GUADEC is the GNOME community’s largest conference, bringing together hundreds of users, contributors, community members, and enthusiastic supporters for a week of talks and workshops.
