Scorecard
Gold, silver, bronze
Rank points across 10 compatible metrics. Lower score wins. Incompatible adapters are excluded from scoring instead of being mixed into the ranking.
| Library | Rank | Score | Category wins or best rank | Analysis |
|---|---|---|---|---|
| GoldReact Data Grid | 1 | 12 | JS gzip, Ready, Jump scroll | Best overall in this fixture: smallest bundle, lowest heap, lowest long-task time, and top smoothness. |
| SilverAce Grid Core | 2 | 27 | Dropped frames | Strong on ready time, scroll settle, low DOM count, and smooth continuous scroll; memory is the main gap. |
| BronzeTanStack Table + Virtual | 3 | 32 | Best rank #2: JS gzip, Ready, Jump scroll | Smooth continuous scrolling, but heap growth is high for this fixture. |
| AG Grid Community | 4 | 37 | Best rank #2: Heap ready, Heap after scroll, Long tasks | Balanced memory profile and low long-task cost, but continuous-scroll FPS trails the leaders. |
| Handsontable | 5 | 40 | Mounted cells | Lowest mounted-cell count, but startup and long tasks are expensive here. |
Metric guide
What the numbers mean
- JS gzip
- Reachable JavaScript after gzip. Lower means less code to download and parse. CSS is excluded.
- Ready median
- The middle of 10 runs from navigation until the adapter mounts and two animation frames pass. Lower is better.
- Scroll settle
- Time for one large vertical and horizontal scroll jump plus three animation frames. It is not an FPS score.
- Mounted cells
- Body cells in the DOM after the scroll. Fewer cells reduce DOM work, but very low overscan can expose blank edges.
Methodology
Same fixture, repeatable protocol
Measurement protocol
- Production bundles in headless Chrome
- Three warmups discarded, then 10 fresh browser contexts
- The same vertical and horizontal scroll jump for compatible grids
- Every raw sample committed with exact package versions

Published-package verification
Ace Grid 1.0.15 vs AG Grid
Thirty alternating-order runs, five discarded warmups, and a fresh browser context for every sample.

On this machine: Ace Grid reached ready 12.2% sooner, settled the scripted scroll 19.5% sooner, and mounted 140 fewer cells. View all raw samples.
Interaction health
Memory, long tasks, and smoothness
Five measured runs after one warmup. Each run performs a two-second continuous scroll in a fresh Chrome context.

Analysis
What the results show
Fastest interactive path
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.
Ace Grid vs AG Grid
Ace Grid remains ahead of AG Grid on ready median, jump-scroll settle, mounted cells, continuous-scroll FPS, and dropped frames. AG Grid currently uses less heap and posts lower long-task totals.
Memory-sensitive apps
Heap-ready and heap-after-scroll numbers favor React Data Grid, followed by AG Grid. Ace Grid's current row-adapter path trades more heap for fewer mounted cells and smoother continuous scrolling.
Compatibility rule
Libraries are ranked only when they expose the same continuous 50,000-row virtualized surface. Pagination-limited adapters stay in raw data, not the leaderboard.
