One of the take-away lessons from this thread for me is that the TPC-* benchmarks are far removed from real world queries. (Maybe if we ask an LLM to use an ORM to implement TPC-H? Ha ha ha!)

To be clear, I'm saying that TPC queries are written by sane adults that know what they are doing, but perhaps lowering rpc tends to help more when the queries are not well-written SQL (which many consultants would argue is the majority of production queries).

 
Cheers,
Greg
