The Analytics tab on /dashboard renders 4 Recharts plus a Flow
Execution Details list with 130+ Collapsible rows. Switching the period
(Week/Month/Quarter) re-rendered everything synchronously: the
pointerdown→paint interaction had INP=434ms (Google "Needs Improvement"
zone), with processing duration alone accounting for 403ms.
Four small changes, no new dependencies:
1. useMemo on usageChartData / toolcallsChartData / flowsChartData so
Recharts receives stable references when only an unrelated piece
of parent state changes (e.g. tooltip hover state).
2. useDeferredValue(executionStats) so a period switch can repaint
the charts first and reconcile the long list as a low-priority
follow-up. While the deferred value is stale we dim the list to
60% opacity, matching the existing dashboard.tsx convention.
3. content-visibility: auto + contain-intrinsic-size on every
FlowExecutionItem. Off-screen rows skip layout and paint entirely
— this is the cheapest possible virtualization, with no deps,
measurement, or scroll math.
4. React.memo on FlowExecutionItem and TaskExecutionItem so parent
re-renders don't traverse the entire 130-row tree.
Measured via chrome-devtools MCP performance trace:
Before: INP 434ms — input 1ms / processing 403ms / present 29ms
After: INP 134ms — input 1ms / processing 112ms / present 21ms
CLS stays at 0.00.
