Simplify Workerman code

[joanhey]

And with better performance

ping @walkor

is is not a matter of (only) performance ...

I mean the idea is to compare fraeworks (perf, overhead, latency, readability ...).

Maybe best to introduce routing feature

I only simplify the code for better readability.
And with the change match() is faster than switch().

I can't add a router, as Workerman don't have any official router, any dev can use any router.

Some frameworks in this bench use Workerman with different routers:

• Mark: Workerman with fastroute
• Nano
• Webman
• Comet
• MixPHP
• Imi
• ...

Ok, for now ...

I mean the endpoints will change so this code will need to be change, but we will do this later ...

PS : Please do not merge, I'll do it
