About StyleBench

+ +

About StyleBench

+ +

StyleBench tests performance of CSS style resolution and style invalidation. Each test run creates a large document and a large stylesheet using varying settings. It then applies a series of mutations to the document and measures the time to update the rendering. The resulting layout is simple, most of the pressure is on selector matching.

+ +

StyleBench uses Speedometer framework for UI and measurements.

Access via 'file:' protocol

To run locally, launch a web server under PerformanceTests directory with 'python -m SimpleHTTPServer 8001' and access via http://localhost:8001/StyleBench. +

+ Individual tests (without measurement) can also be run locally by opening PerformanceTests/StyleBench/resources/style-bench.html +
