I have about 8k movies, 40k series episodes. No issues with this whatsoever... Issues start when adding around 150k tracks to that. Even loading the webpage get slow. Getting rid of 20k tracks then restores functionality completely. Funnily enough it doesn't make any difference what the hardware is. I've tried this on an old Intel i7 Gen 2 mobile CPU, an AMD FX8370 and an AMD 3700 with sufficient RAM, 16GB plus, Emby on SSD's and more.   Agreed. I'm not saying it definitely will. Funnil
