Where did you see that? To be honest, if something is saying 0.0s, then it’s probably a measurement error 😅

Some key things we use to improve RSpec performance are:

- [GitHub - grosser/parallel\_tests: Ruby: 2 CPUs = 2x Testing Speed for RSpec, Test::Unit and Cucumber · GitHub](https://github.com/grosser/parallel_tests)

- [test-prof/docs/recipes/let\_it\_be.md at master · test-prof/test-prof · GitHub](https://github.com/test-prof/test-prof/blob/master/docs/recipes/let_it_be.md) (we wrap this in a `fab!` helper in our codebase)
