I cannot get used to how slow artwork loads and how it doesn't load in the background it has to wait for me to browse the media. Is this normal functionality for emby? It recently asked me to rebuild my library and it's a pain to have to recache all the episode thumbs. they take about 10 seconds to load into kodi on my openelec inter i5 nuc. Prior to emby this was nearly instant, I'm I doing something wrong?
