Awesome, thanks for testing this out! A 3x slowdown is not as bad as 6x, but it's still quite a bit. I also saw a slowdown of ~4x when I tried this experiment

A 3x slowdown is not as bad as 6x, but it's still quite a bit. I also saw a slowdown of ~4x when I tried this experiment on a native Linux x86_64 running ARM - perhaps the Mac -> Linux virtualization slowed it down further.
5x may have been a bit alarmist, but regardless we should brace ourselves for a big performance hit on x86_64 virtualization.
- smspf 6y agoI'm surprised it's only a 3x slowdown. But the single-thread performance of native execution (without emulation) is worse on aarch64, which was expected. Imo, a better benchmark would take into account the multithread performance with/without emulation.
