Github user Ethanlm commented on the issue: https://github.com/apache/storm/pull/2270 @HeartSaVioR Thanks for the review. Yes, you are right. In this case LocalOrShuffle and Shuffle are the same. I just wanted to be consistent with above experiments. Comparing the results of ours, it looks like the `new LocalOrShuffle` will get similar performance with`LocalityASG` on single worker mode. I personally think the numbers here should be good for now (especially those cases with more network latency) and if it gets merged in, we can start working on some follow-up improvements.
