Ah yes so the 4x slower isn’t really a real world case and you’d have to explicitly measure yours - it’s not a fixed slowdown but depends on table size - and it’s for doing many many single inserts in a row, which you’d be batching either way.
Sure the benchmark does not measure a real world application, but I never claimed it was.
Do you have a better benchmark to share?
I thought I was being charitable by using a benchmark published by the database's own authors.
