URL: https://github.com/apache/arrow-datafusion/issues/5999

   ### Is your feature request related to a problem or challenge?
   
   I ran some benchmarks in constrained Docker containers and found that 
DataFusion is pretty close to DuckDB speed when running on a single core but 
does not scale as well as DuckDB when more cores are added.
   
   At 16 cores, DuckDB was ~2.9x faster than DataFusion for this particular 
test.
   
   Cores | DuckDB 0.7.1 | DataFusion Python 21.0.0 | DuckDB x Faster
   -- | -- | -- | --
   1 | 315,630.9 | 318,037.8 | 1.0
   2 | 155,034.5 | 197,257.3 | 1.3
   4 | 75,110.0 | 111,243.1 | 1.5
   8 | 37,584.9 | 73,142.3 | 1.9
   16 | 18,880.3 | 55,071.8 | 2.9
   
   
   
   ### Describe the solution you'd like
   
   I would like DataFusion to scale as well as DuckDB as more cores are added.
   
   ### Describe alternatives you've considered
   
   _No response_
   
   ### Additional context
