Performance tests are designed to catch performance regressions before they reach our
end users. At this time, there is no unified approach for these types of tests,
but `mozperftest </testing/perfdocs/mozperftest.html>`_ aims to provide this in the future.
For more detailed information about each test suite and project, see their documentation:
