Peacekeeper is a free online browser benchmarking tool that measures your browser's ability to render and modify specific HTML elements used in typical web pages. You can easily compare different browsers to find out which one offers the best performance on your system. After the test your browser receives a score indicating its overall performance. By choosing a higher score you are ensuring a faster and smoother web experience within the limits of your internet connection speed.

What does it test? It measures your browser's performance by testing its JavaScript functionality. As JavaScript is a widely used programming language for providing features such as animation, navigation, forms and other common requirements, measuring a browser’s ability to handle these JavaScript functions can evaluate its performance.

What does it NOT test? Peacekeeper is a JavaScript performance benchmark. It does not test your browser’s other features nor does it measure its security functionality. It does not check for W3C conformity, nor does it test external components such as Flash. It does not test, nor is the score influenced by, your internet connection speed or latency.
