   I am also testing with just `filter_pushdown` on: 
   - https://github.com/apache/datafusion/pull/18874
   
   I am going to focus my efforts on profiling these queries which seem to have gotten the most slower:
   ```
   │ QQuery 24    │   215.96 ms │                   253.74 ms │   1.17x slower │
   │ QQuery 25    │   489.11 ms │                   617.52 ms │   1.26x slower │
   │ QQuery 26    │   228.11 ms │                   324.39 ms │   1.42x slower │
   ```
   
   Here is the query: 
   ```shell
   set datafusion.execution.parquet.binary_as_string = true
   SELECT "SearchPhrase" FROM hits WHERE "SearchPhrase" <> '' ORDER BY "SearchPhrase" LIMIT 10;
   ````
   
   Basically my next steps are to profile these queries and see what is slower (and if it is related to filter representation, I will go focus on https://github.com/apache/arrow-rs/pull/8902)
