what does "inf GB/s" mean in this circumstance? I can't figure out exactly how these compare yet; the minify number makes it look like native M1 underperforms Rosetta2.

The benchmark program itself is obviously broken on ARM, as Rosetta is jitting ARM behind the scenes, so you could write a program + compiler that emitted the same ARM as Rosetta. This means it's a problem with the program and not a problem with the M1. I'm not sure what's actually wrong with it yet.
