That is probably on a CI server. During development, I'd probably be running way more than that, at every production or test line written, having a task that watches for file changes and re-runs all tests. Then, having a fast test suite is key. While speeding up the process is always good, tools like lucifer or spork are only masking the problem: loading the whole environment for unit-level tests. Sails, like Rails, promote tight coupling between all parts of the system, which harms test speed, thus harming another development tool: TDD. The more decoupled and isolated you write your business logic, the easier and faster it is to test drive it. Then you simply plug an HTTP interface (with routes and whatnot) that calls into your core.
