If use self.transport.getHandle().send instead of
self.transport.write,it take 30% cpu on 4000 request/s.
Why transport.write take more user cpu?Why twisted performance so poor?
`transport.write` will actually try to deliver your data. `send` will
as likely drop it on the floor as deliver it. Correctness sometimes
costs a little more CPU time.
