Programmer Builds Native Flame Graph Viewer: Conquering Xlib and Performance Bottlenecks

2024-12-25

A Rust programmer, needing to debug Rust Analyzer, embarked on building a native flame graph viewer. Initial attempts using various GUI toolkits proved too memory-intensive. Instead, he cleverly used Xlib, overcoming challenges like scrolling performance, rendering thousands of buttons, and handling mouse interactions. The result: a lightweight, efficient flame graph viewer. This project showcases excellent programming skills and a deep understanding of performance optimization, offering valuable lessons for other developers.
