What are some ways i can make my device run faster?
They are all pretty fast and smooth, because the bloatware is gone. And you can over clock depending on what kernel you choose. I'm just learning myself but you can see the difference.
You can also try other TouchWiz based ROMs with custom kernels, but they may introduce issues the further they stray from stock.
That's pretty much it.
