In this video, Xiaofeng and Jialin Jiao from Roblox introduce their journey in building a robust runtime diagnostic system using Pyroscope. With over 70 million daily active users and 4.4 million creators contributing to the platform, ensuring reliability and efficiency is paramount. They discuss the challenges faced in debugging production issues and the manual, inefficient methods previously used. Through thorough investigation and collaboration with Grafana Labs, they developed an on-demand profiling workflow, enabling engineers to identify and address performance bottlenecks effectively. They share success stories where this system led to significant CPU reductions and throughput improvements. The ultimate goal is to integrate this system seamlessly into their toolchain, ensuring continuous improvement and uninterrupted experiences for Roblox users.
