+#### Optimized Route Lookup
+
+StaticRoute routes are optimized by providing a direct lookup from path to handler. This is different from convential lookups because a match must be found by iterating through the entire list of routes in the router. This reduces the lookup complexity from O(n) - linear - to O(1) - constant.

 ### Handlers
 
 Any class that implements [`HandlerInterface`](src/pjdietz/WellRESTed/Interfaces/HandlerInterface.php) may be the handler for a route. This could be a class that builds the actual response, or it could be another [`Router`](src/pjdietz/WellRESTed/Router.php).
