Understanding your performance result
Run a local browser benchmark for JavaScript CPU work, memory operations, canvas rendering, and animation performance, then receive a device-local score.
The result records only values the browser measured or checks you explicitly confirmed. Unsupported and unavailable values are labeled honestly rather than estimated or invented.
Troubleshooting
Score changes between runs
Power settings, temperature, browser load, and background tasks affect results.
Graphics test is limited
Canvas and browser rendering are not a replacement for a native GPU benchmark.
Mobile score is lower
Thermal and battery policies often limit sustained browser performance.
