I am working on a project (http://github.com/axemclion/browser-perf) to measure front end performance metrics like smoothness and page load time for websites. I would like to try it out on real websites.
If you have a website built by a great front end team and want to see how the smoothness of your web page has changed over commits, I am willing to work with you (for free) and integrate this tool in your deploy or continuous integration process. Please drop a comment and we could work together to try this out.
