It’s so hard to actually benchmark languages because it so much depends on the dataset, I am pretty sure with simdjson and some tricks I could write C++ (or Rust) that could top the leaderboard (see some of the techniques from the billion row challenge!).

tbh for silly benchmarks like this it will ultimately be hard to beat a language that compiles to machine code, due to jit warmup etc.

It’s hard to due benchmarks right, for example are you testing IO performance? are OS caches flushed between language runs? What kind of disk is used etc? Performance does not exist in a vacuum of just the language or algorithm.

I think this harness actually uses JMH, which measures after warmup.
