          Description

          The perf diff between JDK8 -> JDK9 seems to be significant.

          TPC-H Q6 on JDK8 takes 32s on a single node + 1 Tb scale warehouse.
          TPC-H Q6 on JDK9 takes 19s on the same host + same data.

          The performance difference seems to come from better JIT and better NUMA handling.
