Chat Performance Testing
When to use
- Before/after modifying chat rendering code (
chatListRenderer.ts,chatInputPart.ts, markdown rendering) - When changing the streaming response pipeline or SSE processing
- When modifying disposable/lifecycle patterns in chat components
- To compare performance between two VS Code releases
- In CI to gate PRs that touch chat UI code
Quick start
# Run perf regression test (compares local dev build vs VS Code 1.115.0):
npm run perf:chat -- --scenario text-only --runs 3
# Run all scenarios with no baseline (just measure):
npm run perf:chat -- --no-baseline --runs 3
