I ran some profiling of using `datafusion-cli` to run this query ```sql create table test as select * from '/tmp/logs.parquet' ORDER BY request_method; ``` Here is the flamegraph that came from [`hotspot`](https://github.com/KDAB/hotspot). I tried to annotate it the best I can but I am not quite sure how to explain it  I haven't had a chance to study this PR in detail -- but I think we are at the point where we should profile the benches / queries that got slower and figure out what is going on. Given we don't have much (any?) measurements showing a performance improvement I feel like something else must be going on -- This is an automated message from the Apache Git Service.
