My assumption was that the test suite doesn't include performance tests and that it is small and concise enough to exercise most code paths only a couple of times, with only some core code paths being heavily used. That tends to be reasonable (I've yet to see a code base with a branch coverage of 100%), but will obviously not apply to all packages. If you have test for large data sets, for example, the performance may suffer noticeably, as you say. It's usually worth comparing, though.
