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.
