I'm also running this. I haven't noticed much of an improvement. The original poster says he spent hours debugging it, but hasn't posted a single shred of evidence on the process or the result.
Yeah, users' reports of its effectiveness seem to vary wildly.
My suspicion is that it depends heavily on the CPU governor [1] a device uses. Some will see that process running once a second, and keep the CPU at or near max frequency 100% of the time. Others will back down more quickly and you won't see much of a benefit, and still others were probably running at max frequency even before the change, so it wouldn't have much of an effect on them either.
I installed the patch and my CPU frequencies looks like the same, they are not scaling to max all the time. That said it is hard to notice any significant improvement after installing it.
