Why do you not use map when you register a route to check whether the route exists？If there are more registered routes, it will be slower。

Hello @fdsnsf the build-time is slower, not the serve-time, please note that in your title. We use slice instead of map because of Route.DeepEqual but this may change in the future depending on our needs.
