IBM: Memory Power Management Savings Measurable
Phoronix: IBM: Memory Power Management Savings Measurable
An IBM Linux Technology Center has shared that enabling experimental memory power management within the Linux kernel has dropped one of their test system's power consumption by about 2.6% but it's likely even more with experimental hardware...
Seems like a waste of energy!
I don't see a big draw here. Sounds like a lot of talent going into a feature that only supports a few specialized machines.
