Sorry for the delay. Now the tests are fixed per #519. Would you mind rebasing this one please? |

Do we have a rough evidence for this performance improvement? e.g., benchmark.

And what's the impact of disabling this?

See #516 for background and a measurement for a slow case. For the loopback interface I would assume, there are no negative performance impacts for disabling Nagle. I would have assumed it to be the default on loopback, but that seems not to be always the case.
