Marko A. Rodriguez commented on TINKERPOP-1389:
-----------------------------------------------

I was able to fix the performance issue. It had to do with creating too many 
GryoPools due to the transient serialization as suspected. Note that 
{{HadoopPools}} exist for just this situation.

Here are the runtimes for the process computer test suite for Spark.

{code}
        4:13 // GryoSerializer (prior to my last commit — 25 minutes)
        4:49 // KryoSerializer
{code}

> Support Spark 2.0.0
