System Documentation

What problem does it solve?

This skill helps developers identify CPU hotspots and bottlenecks in Rspack builds on Linux by profiling with perf, capturing detailed call graphs, and analyzing hotspots for performance tuning.

Core Features & Use Cases

  • Perf-based profiling for Rspack builds on Linux with DWARF call graphs to resolve kernel and user-space stacks.
  • Generates perf.data and provides hotspot analysis; optionally integrates with Samply for per-CPU thread visualization.
  • Useful for performance optimization during development, benchmarking, and regression testing.

Quick Start

Build the profiling-enabled binding, enable kernel symbols, record a perf profile, and analyze hotspots.
