   The benchmark though should add parallelism by repartitioning after scanning - so I would expect aggregates to be executed in parallel (even though the scan won't be).
   
   Distinct count might be mostly slow as the current implementation is very allocation-heavy.
   
   An additional suggestion to better performance on the benchmark is to add a target-cpu configuration which might yield a ~10% improvement - currently it compiles with the default target.
