"compare" feature in private instance

WPT has a PageSpeed service compare feature here:
http://www.webpagetest.org/compare

Is it possible to have the same “compare” feature in a private instance?

Thanks.

Do you just want the comparison UI for comparing some set of configurations or are you looking to test PageSpeed Service explicitly? The former is available from the video result page: http://www.webpagetest.org/video/view.php?id=140910_ba32185f76c0e8e44142183196c5aeec7692f533 (clicking the “view as data compariosn” link brings you to: http://www.webpagetest.org/video/view.php?id=140910_ba32185f76c0e8e44142183196c5aeec7692f533&data=1 ).

If you’re looking to test the PageSpeed Service itself, that isn’t supported.
