[jira] [Created] (SPARK-7360) Compare Pyrolite performance affected by useMemo

Xiangrui Meng created SPARK-7360:
------------------------------------

             Summary: Compare Pyrolite performance affected by useMemo
                 Key: SPARK-7360
                 URL: https://issues.apache.org/jira/browse/SPARK-7360
             Project: Spark
          Issue Type: Task
          Components: PySpark
            Reporter: Xiangrui Meng


As discussed in SPARK-6288, disabling useMemo shows significant performance on some ML tasks. We should test whether this is true across PySpark, and consider patch Pyrolite for Spark.
