After a form submission, a fetcher submission, a call to useRevalidator, or a navigation that changes params or search params, Remix re-runs the loaders of every currently matched route. A root loader that queries the database on each mutation is a common reason forms feel slow.
Export shouldRevalidate from a route to control it. The function receives currentParams, nextParams, formMethod, actionResult and defaultShouldRevalidate, and returning false skips that route's loader. It is not called on the initial document load, so it cannot affect the first render.
Be careful with it: opting out means the route keeps serving the data from its previous load, so any mutation that changes that data must revalidate explicitly or update it in place. Under single fetch the loaders that do run are batched into one request, so the saving is server work rather than round trips.
