Rspack Tracing & Performance Profiling

When to Use This Skill

Use this skill when you need to:

1. Diagnose why an Rspack build is slow.
2. Understand which plugins or loaders are taking the most time.
3. Analyze a user-provided Rspack trace file.
4. Guide a user to capture a performance profile.

Workflow

1. Capture a Trace

First, ask the user to run their build with tracing enabled.
