Battery usage compared to vm


My primary reason for switching from vagrant to docker on OS X was a feeling that providing lightweight virtualization it should have been lighter on system resources and conserve battery life compared to virtual box VM running centos minimal.

But sadly I don’t see any difference.

I’m interested if anyone has done more in-depth research, and has some numbers instead of my hunch looking at activity monitor.

I’d also be glad to contribute to the test, not sure how to compare these two in a scientific manner yet though.
