Nick Pentreath commented on SPARK-15447:
----------------------------------------
Added a second tab to the sheet for testing DF-based API from 2.0.0-SNAPSHOT vs
1.6.1 for SPARK-14891. Again, 2.0 is faster and no performance regression.
> Performance test for ALS in Spark 2.0

> We made several changes to ALS in 2.0. It is necessary to run some tests to
> avoid performance regression. We should test (synthetic) datasets from 1
> million ratings to 1 billion ratings.
> cc [~mlnick] [~holdenk] Do you have time to run some large-scale performance
> tests?
