Hello,   running Emby 4.5.4 on a QNAP NAS (installed the QPKG). I do have a large collection of photos. They are organized as follows: photos - album-1 |_photo-files.jpg - album-2 |_subfolder-1 | |_photo-files.jpg |_subfolder-2 |_photo-files.jpg For one folder, the thumbnail generation is way of . e.g. 15000ms vs 50ms in other folders Here is a log snippet of the "bad ones" after enabling debug logging - there are a lot of those entries. 2021-01-20 12:23:28.818 D
