      At least for jstests, there is huge variance in test runtimes which often results in the longest running test of a suite extending the entire task by minutes, even for "reasonable" long running tests.

       

      In mongo-task-generator create suites, the tests are already in sorted order by runtime.

       

      One caution is we don't want to lose the benefit of shuffling tests as a mechanism for flushing out flaky tests.
