That's like 25 minutes of just waiting for thumbnails to be > generated/load. Hi Michael, The face thumbnail is generated from the original image when the face is detected in the scan. The thumbnail image is then saved to the thumbnail DB. We also have a thumbnail caching service in digikam that keeps a portion of the thumbnails in memory. I'm not sure, but I think Gilles might be referring to refreshing (rebuilding) the thumbnail cache, and not the thumbnail itself since the thumbnail shouldn't change once it's been written to the DB. The thumbnail will get rewritten to the DB if there is a change to the face region or editing done to the image that changes the dimensions. Can you provide the specs of your system? How fast is the CPU, what kind of storage (local SSD, network share, etc...), and probably most importantly, how much memory do you have?
