 In this benchmark, Fox performs as well as `Gin` and `Echo` which are both Radix Tree based routers. An interesting fact is
 that [HttpTreeMux](https://github.com/dimfeld/httptreemux) also support [adding route while serving request concurrently](https://github.com/dimfeld/httptreemux#concurrency).

 Now let's see how expensive it is to access a parameter. The handler function reads the value (by the name of the parameter, e.g. with a map 
 lookup; depends on the router) and writes it to `/dev/null`
