The tests we would most likely be interested in are located in the ''tinderbox-standalone-tests'' subdirectory. Based on a quick scan of the perl files there, the ''test-mozilla.pl'' file in that directory seems to drive the tests located in the ''Tests'' subdirectory which seem to contain a lot of performance tests. The arguments that the test subroutines receive (such as build directory and binary name) seem to come from the ''Settings.pm'' file located in the ''mozilla/testing/Util'' directory.
