   @scsmithr  how did you get the numbers you report in 
https://github.com/apache/arrow-datafusion/issues/7001#issuecomment-1675625184 ?
   
   I believe the benchmarks default to using only 2 cores: 
https://github.com/apache/arrow-datafusion/blob/ed85abbb878ef3d60e43797376cb9a40955cd89a/benchmarks/src/options.rs#L29-L31
   
   So if you ran the tests without specifying `--partitions 16` or whatever 
they probably aren't using eveything
   
   I wonder if we should increase the default number of partitions to the core 
count in the benchmarks 🤔
