I have my RPi2 hard-wired. We have 155/20 internet speeds. However, no matter what the add-on, it seems slow to load movie marquees/posters/thumbnails. We can navigate around just fine. It also doesn't seem to matter if they've loaded before. I'm assuming I need to do some type of better cache setting? Thanks in advance for the answer(s) and please speak in layman's terms.
