Performance

Performance is a product feature. K-Web should feel instant.

Budgets (initial)

• Hover preview response: under 50ms in typical cases
• Selection commit: under 150ms
• Initial load (demo web): under 2s on a mid phone connection
• Graph render: stable 60fps while panning in small graphs

Strategies

• Precompute neighbor lists and time buckets.
• Avoid full re-renders on hover, update only what changed.
• Prefer incremental layout updates.
• Keep DOM small, virtualize lists.

Definition of done (perf)

• [ ] No obvious jank in hover and click.
• [ ] Basic profiling notes exist for the graph view.
