The cost you've found is just an estimate produced by the planner and
not a good number to performance tune with. I recommend reviewing the
fragment and operator metrics written to the query profile after
execution. If you are further able to isolate the query so that it's the
only thing running then OS and JVM counters can also be recorded.

Please advise or any documentation pointer will help. thx
