The plaintext benchmark looks fast, but note that the router is simply 
matching on the exact length of the path name used in the benchmark:

```
     override void onComplete(HttpRequest req) {
         string path = req.uri;
         if(path.length == plaintextLength) { // plaintext
             respondWith("Hello, World!", 200, textHeader);
         } else if(path.length == jsonLength) { // json
             JSONValue js = JSONValue(["message" : JSONValue("Hello, 
World!")]);
             respondWith(js.toJSON(), 200, jsonHeader);
         } else {
```
