Explication technique
Web Workers run integer and floating-point loops off the main thread, keeping the interface responsive. Throughput is the number of completed operations per second across workers.
A browser workload is not a calibrated CPU benchmark. Thermal throttling, background tasks, browser scheduling, and device power limits make results unsuitable for comparing different devices. Stop immediately if the device overheats.
Dépannage
Device becomes very hot
Stop the test. Thin laptops and phones may throttle quickly. Allow the device to cool before another run.
Fewer workers than requested
The browser may limit worker count or available memory.
Test stops early
Some mobile browsers suspend background tabs. Keep the page visible and the screen on.
Throughput drops over time
Thermal throttling or battery saver is likely. This is an observation, not a fault diagnosis.
