# Studio Performance ## Minimize frame subscriptions Keep dependencies on the current frame as low in the component tree as possible. Prefer imperative timeline state reads such as `getCurrentFrame()` over `Internals.Timeline.useTimelinePosition()` for event handlers and other on-demand logic. Use `useTimelinePosition()` only in the smallest leaf component whose rendered output must change with the frame. If a parent reads the frame only to pass it to a child, extract a frame-subscribing child so the parent and its other descendants stay stable. ## Memoize stable boundaries Wrap components in `React.memo()` when they can safely skip parent-driven renders. Confirm that their props remain referentially stable across frame updates: newly created objects, callbacks, styles, or React nodes defeat shallow memoization. Stabilize those props only where it is natural; avoid custom comparators that ignore behaviorally relevant changes. Context subscribers continue to update through memoized ancestors. Prefer a memoized stable parent with a small frame-subscribing leaf over making the whole subtree reactive to the current frame.
