It is actually slower, even if not by much. If you have a fast CPU
supporting virtualization and a lot of RAM, you can have it run close
enough to your real computer that you don't notice much of a
difference.

Provided you have a minimal set of processes running on both your real
hardware and your chroot, the chroot will be faster for building than
keeping minimal processes running on your real hardware and the VM.
The only advantage to a VM for building packages is to test them after
they've been built.

Needless to say, there are other uses for a VM outside building packages.
