fmcquillan99 commented on issue #467: DL: Improve performance of mini-batch preprocessor URL: https://github.com/apache/madlib/pull/467#issuecomment-573256832 @reductionista Looking at the 5k buffer size runs, can you pls just double check in the code that we are skipping the normalization if the normalization factor is `1.0` or `NULL` ? I am asking since there is no performance improvement on my small test cluster when I skip normalization.
