I installed the latest version of Lightroom Classic to a desktop with Windows 10 64-bit OS, Intel core i-7 processor, 16 GB memory, 4GB AMD Radon GPU, both 256GB SSD and 1 TB 7200 rpm drives. I am trying to add photos on my hard drive to a new Catalog. The source folder and sub-folders have 18,000 JPG photos (initially adding only about 1/4 of my photos to keep it managable). I used the default add catalog settings and made sure to "add" not copy or move. The process has now run for more than 6 hours (over three days) and is still not done. Is this normal for Lightroom? I started a new subscription but it does not seem worth if I can't even import photos to a catalog without taking days. Please anyone with clarification or suggestions?
