Linux 4.7 CPUFreq Schedutil Testing vs. P-State

First up with some single-threaded audio encoding tests, CPUFreq with Performance/Ondemand/Conservative/Schedutil were close to the same. However, the P-State driver with its governors were noticeably slower than the other CPUFreq options -- except for CPUFreq Powersave. It's odd that CPUFreq Powersave was performing so much slower than CPUFreq Conservative for this test and that P-State on Linux 4.7 was also trailing behind a lot more than we tend to see.

With x264 multi-threaded video encoding, Schedutil came in second place for best performance right behind the CPUFreq performance governor.

Schedutil was also right behind the CPUFreq performance governor for the timed Linux kernel compilation test.

Schedutil came in first for the Open Porous Media benchmark.
