<div dir="ltr">That doesn't seem too surprising to me. I have aarch64 Fedora running in UTM on an M1 Mac and it runs very fast. UTM is basically Qemu + Apple's bare metal hypervisor framework, so you'll get almost native speed running an ARM Linux distro. And macOS isn't a very fast or efficient OS compared to Linux in many ways, which may explain the speed boost running OpenSCAD on Linux at close-to-native speed in a VM on macOS.</div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Nov 16, 2021 at 6:22 PM Doug Moen <<a href="mailto:doug@moens.org">doug@moens.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">There's a thread on the OpenSCAD mailing list talking about a compute-intensive OpenSCAD program that takes 17.5s on an M1 Pro under MacOS, and the same job takes 12s on Ubuntu running in a VM on the same machine.<br>

Interesting that M1+Linux is much faster.<br>

Even though Asahi Linux isn't ready yet, someone is running Arch Linux on an M1 macbook pro.<br>
