Ahh.. that could be, we definitely didn't get a chance to give it a whirl on apple silicon. If you get a chance to give it a go, I'd appreciate it very much if that resolved it.
I'll see if I can give it a try if I happen to get a chance on a macbook myself. Thanks for that clue towards unraveling who the ultimate performance culprit is, we'll root them out! 🤘
