Thanks for the benchmark, I didn't know half these projects existed.

One thing that affects Gorilla mux is that this test is putting all the routes at the top-level instead of constructing subroutes based on the logical route hierarchies.

Certainly the fact that HttpRouter constructs that prefix tree for you is a huge feature, and the speed is impressive, but it's not a typical/canonical usage of Gorilla mux.

I don't know if that's the case with the other routers or not.
