4) I haven't changed anything concerning the images. The data from Kodi is in memory. Images are handled separately. For each movie you have a poster/background. I use the original and don't scale it. Would not be great if you have a low res version as a background. So suppose you have a library of 300 movies, each with a poster and background. A background is around 3 MB average...a poster 1 MB....4 MB for one movie 300 x 4 MB = 1200 MB of memory needed.

Sorry with images i meant poster of each movie. how about scaling the poster, to speed up the process? In official remote kodi is some how handling this very well and the resolution of each poster is very good. Maybe they have used a low res but still have good quality to display it?

I wish it was always that simple. Keep scaled down images in memory is no problem. Other possible influences make it complicated. Suppose you have the images in memory and you decide to change the poster/background (in either the app or Kodi, I don't think the official Kodi remote has a select fan art option). I have to check if the image has changed. Sometimes you have to make a compromise to make the code not that complicated and accept it could be a little bit slower (for now). It's not that it can't be done.

Maybe with meridius new theme where he can show around 13 poster each time is going to improve this, right now its 24 poster that need to be loaded immediately. But I don't know, we will see
