This is irrelevant for unit tests. Performance testing does not make any sense in build environment, you need to do it in an environment close to production and that’s completely different test automation scope.
You can see this stuff often even in test workloads. But even if you disregard that kind of issue, you still have stuff like needing to integrate networked database connections into e.g. event loops, which you don't really need to do for things like sqlite.
