Is your feature request related to a problem or challenge?

I found a extremely strange different results from two dfbench binaries...

  • The first one is built by running cargo build --release --bin dfbench in datafusion dir.
  • The second is built by running cargo build --release --bin dfbench in datafusion/benchmarks dir.

And in my local, I found in main branch:

  • The first one cost 9200+ms when running q22 in clickbench.
  • The second one cost 8800+ms when running q22 in clickbench.

In my branch in #11802

  • The first one cost 8800+ms when running q22 in clickbench.
  • The second one cost 9200+ms when running q22 in clickbench.
