Benchmark! That's how. Order the least amount of resources and then benchmark your app to see how well it's performing. If your goal is handle 100 req/s, then benchmark with that goal in mind. Your benchmark unit tests need to touch the whole stack (Ruby & SQL). As for the 24-hrs idle time, run a periodic script that keeps it alive (by simulating a valid app action). I'm not a Heroku user.
