How you want to increase the speed of parallax? Maybe you mean to increase the speed of nice scroll? Because if this is what you mean, you can do this under Theme options > Addons & Plugins > Addons section.
We understand very well what you mean but on our side both sites works exactly the same. And the only option we have responsible for speed scrolling is the option we gave you above already. There is no other option included if this is not what you are looking for, then we do not have anything else unfortunately.
