Piotr Nowojski commented on FLINK-27921:
----------------------------------------
Benchmarks maybe could be rewritten in such way that the measuring starts once
for example all source subtasks are running, using some custom source. But if
we can disable this feature for benchmarks, that would be simpler.
Separate thing to consider is whether we accept the increased start up cost
introduced by this ticket.
