To be fair, that’s likely because the Android subsystem is a virtual machine - not running multiple sets of system services / CPU emulation on a computer will make it faster pretty much universally.
It's not just the virtualization, ChromeOS has had a lot of work put into performance. The low-end ARM Chromebooks use the same hardware as budget Android devices, and they're noticeably faster. My Android phone uses more RAM doing nothing from a fresh boot than those Chromebooks even have.
That’s a good point actually. Windowed app performance on Android apps is especially bad since they’re not designed for it (most of my experience is on Android-x86, but window resizing performance is not great)
