Re: Strange: Rosetta faster than M1
I really think you should start by asking this question over in the Swift forums, in case there is some compiler-specific answer that can immediately explain the result. It could be a compiler code generation deficiency, but there are many other possibilities. For example, a colleague of mine speculated that there could be reasons why the M1 Mac ran the Rosetta translation on a *performance* core, but ran the Apple Silicon version on an *efficiency* core.toggle quoted message Show quoted text
You can also investigate the performance yourself, by running (say) the Time Profiler template in Instruments. It’s unclear which instrument might provide informative results, so you might need to try a couple of different templates, focussing on different things.
This might ultimately be an Apple support question, but I’d imagine there are numerous people on the Swift forums who’d enjoy puzzling out the answer. :)
