Build with Naz : Claude Code + Rust profiling and perf
This video dives into a powerful code optimization workflow for using Claude Code and other tools (flamegraph, inferno, etc) showcasing how to install and configure the tools and create a feedback loop to effectively measure the impact of code changes (to performance).
We'll walk you through the complete setup of our environment, including the integration of Rust, rust-analyzer, and a custom AI coding tool (claude code and mcp server). The core of the video focuses on a practical optimization example, where we use flamegraph and inferno with perf-folded output to identify performance bottlenecks and the analyze them using Claude Code.
