Interesting - I wonder if this is something related to how sampling is done with `samply` (which I learned about from @comphead, thanks). I can confirm it shows up as "very heavy" with TPC-H benchmarks as well (just the first queries I test), but I believe in earlier profiling it didn't really show up. I'll compare some profiling with `cargo flamegraph` to confirm this is the case. -- This is an automated message from the Apache Git Service.
