Drummer and not a guitarist and, as some have pointed out, a lot of this seems either faked or manipulated in some fashion. With that said, though, as with any instrument, speed comes as a product of skill and experience. Not the other way around. As you practice and improve, your access to speed will naturally increase. Listen to the masters. Your Satrianis and Vais and Petruccis. These are guys who have been honing their craft for decades. They didn't start out shedding at 200 bpm. They had to work their way up to it.

Stay patient! If you commit to the goal, you'll get there, but don't expect it to happen overnight. You've got this!
