   > I think I want to start on a parquet end-to-end benchmark of some sort. 
The arrow_reader bench is _so_ sensitive. On my workstation I was seeing the 
BinaryViewArray bench taking about 10% longer consistently across the various 
permutations. Then I merged the latest from main, and one bench regressed 
further, but the others were consistently faster than baseline. I then reverted 
one change in this PR...the first regression nearly went away, but the others 
then regressed significantly. 🤯

   That would be amazing - I agree the benchmarks could definitely improved. 
Shall I file a ticket ?
