   Unfortunately, even after adjusting the benchmark on this branch I still 
don't see major changes in https://github.com/apache/arrow-rs/pull/7428.
   
   I will look more deeply tomorrow

   cargo bench --all-features --bench arrow_reader_row_filter -- 
Utf8ViewNonEmpty
   ```
   
   Main compared to https://github.com/apache/arrow-rs/pull/7428
