Neat but please note nobody has tested any of the settings. Speaking for myself, I am able to experience an improvement (more snappier) with swappiness = 30. The settings have to be carefully tested and benchmarked in order to declare them both usable and safe. One could argue "if it doesn't hurt, it doesn't matter" but I don't recommend to the general public changing too many settings you don't know effect about. That said, if anyone can explain how to benchmark the effects I'd love to share the benchmarks from my machines.
