Two years ago, I got a job to evaluate cross-platform benchmarks for comparing Windows and Android.
Usually, Web-based benchmarks focus on only Java-script and HTML5 functionality. I found WebXPRT is easy to use and includes the tasks that you do every day. It reliably tests the user experience and gives a simple score for comparison. I suggested to our manager that we use it to evaluate our platform and he agreed.
Recently, Chromebooks have become very popular. Testing the battery life of Chromebooks has been difficult because you have needed to use the power_LoadTest image from the Chromium project or the test image from the Chrome OS Partners Web site to do power load testing. Without reimaging the system, you couldn’t test battery life. Because CrXPRT is designed to test battery life as well as performance on ChromeOS, this extra step is no longer needed. We can run CrXPRT without updating the test image, which is very useful in our battery life testing.
The advantage of XPRT benchmarks is that they are easy to use and give real-world results. The disadvantage is that they are not yet popular on review sites.
