I am currently measuring Cosmo UI performance using Windmill, there
to measure the length of time any action takes. In the near future we
will be sending this back to the server and using python to store and
analyze it, but for now I am working on a small ajax app to parse the
current performance output and graph it so that we can compare
performance times for each checkpoint we test with Windmill. As soon
as I have a demo I will send out the url.
