Those are some opinionated tests for performance checks. What both symfony and laravel routers achieve with their routers isn't comparable with this router library. If you want to go a bit further and implement ultimate fastest routing, create an associative array, routes as key, callable's as value. Will it be fast, yes. Will it be usable, no.
