I like Rapidoid at this point. It has both high-level and highly-performant APIs.

This is how handler is defined in Rapidoid
```
HttpStatus handle(Channel ctx, boolean isKeepAlive, Req req);
```
I don’t see where it returns a response in a functional way. This is how static files are served internally:
```
							HttpIO.INSTANCE.write200(HttpUtils.maybe(req), ctx, isKeepAlive, contentType, bytes);
							return HttpStatus.DONE;
```
So it’s more or less the same, no?

No, I don't mean it works as I like.
I mean that it has fast API and handy API apart.

Also, looking at some parts of Rapidoid, I seriously question if it standards compliant… 
For example, headers are `Map&lt;String, String&gt;`, so I’m not sure how it handles multiple headers with the same name…  Same for params.
