[jira] [Created] (SPARK-18224) Optimise PartitionedPairBuffer implementation

Adam Roberts created SPARK-18224:
------------------------------------

             Summary: Optimise PartitionedPairBuffer implementation
                 Key: SPARK-18224
                 URL: https://issues.apache.org/jira/browse/SPARK-18224
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
    Affects Versions: 2.0.1, 1.6.2
            Reporter: Adam Roberts
            Priority: Minor


Like the PartitionedAppendOnlyMap improvement we can make (SPARK-18223), this change takes advantage of comparator wrapping, we have observed a 3% performance increase with IBM's SDK for Java and OpenJDK on PageRank due to the inlining benefit
