RE[2]: Thanks Kernel Developers!

Member since:

OS X has piss poor power management in and of itself, it's the Apple drivers and tweaks that allow it to be efficient. You can do this in Linux too, but it takes more work and some understanding of how ACPI works.

Based on what evidence is it 'piss poor' or is this more 'speaking out of your ass' rather than using empirical data?

The efficiency in terms of power management has as much to do with the kernel as it has with the user land applications and how they're written. If an application is polling non-stop for a device to be inserted then it won't matter how efficient the kernel is given that an application in user space is constantly waking the CPU from its low power state.
