The Idle Power Use Of The Past 19 Linux Kernel Releases

This morning I published the Power Consumption and Efficiency Of The Linux Kernel For The Last Three Years article containing power consumption data for an Intel Haswell system going back to the Linux 3.11 kernel through Linux 4.9 Git. Those were some interesting power consumption numbers under load while here are the idle numbers.

Linux 4.9 Is Showing A Performance Boost On More Systems

Earlier this week I posted some benchmarks of a Core i7 6800K Broadwell-E system seeing performance boosts under Linux 4.9 and it turns out it's looking more widespread than just affecting a niche system or two. When testing a more traditional Intel Haswell desktop, Linux 4.9 Git is seeing more wins over Linux 4.8 and 4.7 kernels.
