The slowest test in terms of setup time (fixtures, everything in setUp) is: zamboni.mkt.ratings.tests.test_views.TestCreate And of the 20 slowest tests, a couple of the tests in that class are the slowest, eg: zamboni.mkt.ratings.tests.test_views.TestCreate.test_body_has_url zamboni.mkt.ratings.tests.test_views.TestListing.test_detail_local_reviews_only etc.. clocking in at around 3.5 seconds a test.
Got around a 30% speedup. Most of the time is spent in the ORM, of course. https://github.com/mozilla/zamboni/commit/ec681e2f867dcc6c88117c6199167779eea73968
It still shows up as the slowest test in the site however. http://cl.ly/image/1M3w152X3p3G
making our tests faster is going to require an overhaul of more than a few things.
