ClickBench wants engines to run "default" configs, which means that in reality 
we would have to make it the default for everyone. 
   
   Yes, that is my understanding too (it is at least the spirit of the 
benchmark)
   
   > Currently it's something like 10x faster in a lot of cases but 2x slower 
in some cases... [@alamb](https://github.com/alamb) is working hard on getting 
to be the default everywhere, but I don't know if we are ready yet.
   
   Yeah, actually i am working with @hhhizzz on this in 
https://github.com/apache/arrow-rs/pull/8733 (well, I am reviewing and @hhhizzz 
is doing all the work)
   
   > I think it's okay if Q23 is only 15% faster for now and we make it 10x 
faster next release or something. As long as it's not a regression...
   
   
   Yes this is my thinking too.
