Peacekeeper support ended in 2015
Peacekeeper is a universal browser benchmark for measuring JavaScript performance. Since its release in 2009, more than seven and a half million people have used Peacekeeper to compare browser performance. But by 2015, competition between browsers had largely shifted from speed to features.
Modern browsers are typically fast enough on a wide range of hardware, and the differences in speed in everyday use are trivial. Pure JavaScript performance benchmarks are no longer as relevant as they once were. A browser's features, extensions, and memory use are now much more likely to be the deciding factors.
Support for Peacekeeper ended in julho de 2015, and the service was taken offline in março de 2018.
Alternatives
While we no longer make a benchmark for comparing the performance of different browsers, our PCMark benchmarks do include tests for measuring the web browsing performance of your hardware.
PCMark benchmarks are based on real-world tasks such as web browsing, photo and video editing, writing, spreadsheets, video conferencing, and other common activities. Tests based on everyday tasks are more useful than the narrow, synthetic workloads typically found in JavaScript benchmarks.
For Windows PCs, we recommend PCMark 10. For smartphones and tablets, we recommend PCMark for Android.
