reminisce commented on issue #13143: [MXNET-1206] Support NDArray indexing with None and Ellipsis URL: https://github.com/apache/incubator-mxnet/pull/13143#issuecomment-517894875 @kohr-h Thanks for the reply. @zoeygxy did some benchmark and found that 1. Indexing operations that should return views are slower than before. 2. Indexing operations that should return newly allocated `NDArray`s are faster than before. We can get this PR merged first and take care of the cases that return views in a later PR. PS: benchmark results [old_indexing.txt](https://github.com/apache/incubator-mxnet/files/3463396/old_indexing.txt) [new_indexing.txt](https://github.com/apache/incubator-mxnet/files/3463397/new_indexing.txt)
