The TestFailures page loads a bunch of data from build.webkit.org that doesn't change. If we were to cache some of this data in window.localStorage (or similar), we could avoid reloading the data every time the page is viewed by a particular user. This would probably speed up loading quite a bit.
Data we might want to cache: 1) The list of old builds for each tester 2) The set of failing tests in each of those old builds We'd want to prune the cache from time to time. I think a strategy that would work well is: * Whenever we finish finding revisions to blame for all currently failing tests, throw away all data for all revisions older than the oldest "passing" revision identified. E.g., if all currently failing tests were passing in r12345, we could throw away all data for r12344 and older.
