lacking issues with kutetheme

I am just reporting that the theme is very slow to load especially using the old devices ie. ipad2,iphone 4&5 , we even tried testing it in so many devices like for instance if you would compare amazon for instance its very smooth in loading in all devices regardless of the device (I also tried the live preview of the theme and it has the same problem), I am just wondering if there is anything that you could do to make it abit more smooth and make it running a bit faster than that ! suggestion you could remove the animated sliders in the main home page. I am just wondering if you could make a modified version without anything that would make it slower to load like the animated sliders in the homepage or removing whatever makes it faster and smooth,
