alt Hacker NewsThe thing is, performance in that particular context hardly matters, unless you're forcing users to switch pages faster than 1 page per second. Even if each resolving takes 0.1 seconds (which be bad, don't get me wrong), 99% of users wouldn't notice a thing, and if you're a small agency/shop/company/team, focusing on more general things tends to be time spent better.
I have a hard time imagining how one would implement a router that took a full millisecond to resolve a path in a typical case.
