SUMMARY I have a photo collection of 100_000 photos that I want to import. Digikam takes about 1 week for that job. During that time, it uses only a single thread, even though my computer has 8 cores. STEPS TO REPRODUCE 1. Import a folder containing 100_000 photos. 2. Wait 2 days, then look at the progress. OBSERVED RESULT Digikam is still importing the photos. There is no useful progress bar. During the import, Digikam crashes whenever I click around in the timeline. After a crash, Digikam does not offer to report the crash. EXPECTED RESULT Digikam can import a reasonably large photo collection in a single day. During the import, I can already work on the imported photos, for example, search for duplicates. Importing the images happens in a background thread, it does not affect the UI. Digikam does not end up as "not responding" even for a folder containing 100_000 images. SOFTWARE/OS VERSIONS Windows: 10
If you start with digiKam, you don't import images via the import tool. The import tool is for importing images from camera, memory card, USB. You simply add a collection to your existing image directory. Maik
And since, depending on the device drivers used, multiple threads are not possible, I'll close here. Maik
