Warning: These results are preliminary - use with caution (they may e.g. be from different browser versions). Official results are published on the results page.

The benchmark was run on a MacBook Pro 14 (48 GB RAM, M4 14/20 Cores, OSX 26.3), Chrome 145.0.7632.76(arm64) using the puppeteer benchmark driver with reduced tracing.

After chrome 119 official results we've changed a detail for the benchmark: We now open a new tab for each benchmark iteration, earlier runs reused the tab per benchmark and implementation.

Starting with chrome 118 the benchmark uses a weighted geometric mean to compute the overall result.

Starting with chrome 137 we're benchmarking the non-keyed implementations only for even chrome versions.

Keyed results

Keyed implementations create an association between the domain data and a dom element by assigning a 'key'. If data changes the dom element with that key will be updated. In consequence inserting or deleting an element in the data array causes a corresponding change to the dom.
