ScorecardGold, silver, bronze

Rank points across 10 compatible metrics. Lower score wins. Incompatible adapters are excluded from scoring instead of being mixed into the ranking.

Metric guideWhat the numbers mean

JS gzipReachable JavaScript after gzip. Lower means less code to download and parse. CSS is excluded.<br>Ready medianThe middle of 10 runs from navigation until the adapter mounts and two animation frames pass. Lower is better.<br>Scroll settleTime for one large vertical and horizontal scroll jump plus three animation frames. It is not an FPS score.<br>Mounted cellsBody cells in the DOM after the scroll. Fewer cells reduce DOM work, but very low overscan can expose blank edges.

Interaction healthMemory, long tasks, and smoothness

Five measured runs after one warmup. Each run performs a two-second continuous scroll in a fresh Chrome context.

AnalysisWhat the results show

Fastest interactive path<br>React Data Grid leads the overall scorecard because it combines the smallest runtime heap, no median long-task time, and near-120 FPS continuous scrolling.
