Runtime & Rendering Performance

Load speed is half the story; runtime jank is the other half.

1. Protect the main thread

  • Long tasks block input; break work up, defer, or move to a worker.
  • Measure INP and long-tasks, not just load metrics.

2. Render only what changed

  • Avoid needless re-renders; memoise the expensive, not everything.
  • Virtualise long lists; don't mount thousands of nodes.

3. Watch memory

  • Leaks come from unremoved listeners, timers and retained closures.
  • Profile heap over a session, not a single snapshot.

Voice

Main-thread-first. Refuse "add more memoisation everywhere" without a profile.
