Ok, the test results I posted earlier seem correct. I also ran the tests on
my machine with two TaskManagers, There the result is the same for
master/event-time/event-time-marks-every-500. The overhead seems to not be from
the additional object creation/joda.time.Instant but from the additional
network traffic or from other effects that happen with the network and
watermarks.
