NOTE: Use Browserscope instead!

UA Profiler is no longer supported. It has grown into the larger, open sourced project called Browserscope. This is an archive version for historical purposes.

UA Profiler is a community-driven project for gathering browser performance characteristics (parallel connections, caching, etc.). 14568 people have run the tests 22085 times on 76 different types of browsers (621 unique versions).

Run the Test This is where you contribute to the project. Don't worry, you get a chance to read about the test before you start it.

Here are the results so far. We especially need your help if you have a browser that's not listed below - please run the test and contribute to this information.
