 #### 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.

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.
