wsry commented on issue #11088: [FLINK-16012][runtime] Reduce the default number of buffers per channel from 2 to 1 URL: https://github.com/apache/flink/pull/11088#issuecomment-588129045 I have tested reducing the exclusive buffer from 2 to 1, and then put them into floating buffers instead. It has no evident influence on the performance. I also tried to tune the ```floating buffer per gate``` to see how many floating buffers can compensate the regression, unfortunately, the results show that we need about 1000 floating buffers which means we can't reduce the buffer of upstream if we expect for no performance regression. Can we implementation dynamic policy directly without first reducing the ```buffer per channel``` statically? Any suggestions? @pnowojski @zhijiangW
