Where does "81% latency reduction" come from? Static routes are just a single dict-lookup in bottle, and up to 100 dynamic routes are packed into a single regular expression which already has a Trie-like structure and is implemented in C. I kinda doubt that a pure-python tree lookup is any faster. Please provide the code you used for your benchmark. You also failed to implement the method fallback properly, and I wonder why the other parts if the Trie lookup covers both static and dynamic routes.

Tests pass, but only because you left in the old logic as a fallback, masking the incomplete method handling of your approach.
