No overclocking/undervolting without root. You need a custom kernel for that and root is required to install a custom kernel.
Increase scrolling speed? There may be something in Settings > Developer options. I know you can increase the drawing rates in there. Otherwise root and add a custom ROM or some tweaks packages. A lot will depend on what device is being discussed.
