This is to be expected. bhyve is a hypervisor, which means that code
runs on a real CPU with the performance more or less comparable with
non-virtualized system. qemu-system-aarch64 is an emulator, it
emulates CPU in software. There is no way to get the same level
of performance from the software CPU implementation as from the native
code.
