Sometimes, while developing tests, the test suite will take too long to run. In such a situation I’m interested in optimizing the test suite by removing test cases from some test sets. How to tell which test sets execute for too long, though?

This question concerns the Julia Base tests, in particular, `make test-rational`, for example.
