in other words... all it does is shut down programs (the only things that use threads and ram) to free up threads and ram... and services are just programs that run in the background... gamebooster and stuff like those just do some of the work for you that want to be ignorant... about how your machine works, and whats required for it to work and what isn't
guess what I'm saying is... a machine is only so fast... aside from overclocking, no program is gonna speed up your computer, just turn off stuff you can turn off yourself, and in doing so yourself, have 1 less program running because of not having gamebooster or whatever you're using running too
