Full Width Slider Loading very Slow

Hi,

I can’t get either the full width slider or the easy slider to work properly. When i use the full width slider it looks perfect. It goes from the edge to edge of the boxed page filling the content area. The issue is load very very slow, (only the first time until things are cached) then if you click the arrows to move to the next slide before it’s fully loaded (many seconds) the entire slider disappears.

To avoid this, i tried using the easy slider, and this loads instantly (with all the same images) but no matter what size i make the images, they have large margins around them. I need this edge to edge. I’ve turned off all plugins, i’m using the latest version of WP and the Theme. Please help:)
