The problem with the current digikam/libkface implementation is 2 fold. First,
it blocks so much memory. I think most of it is reclaimable as needed. But the
other problem, of not using all available cores, is more annoying. It ends up
taking way more time than necessary.
PS: Yes. I did select "Work on all cores" in the Advanced Tab.
Reproducible: Always
Steps to Reproduce:
1. Scan collection for faces
2. Ensure "Work on all cores" is selected
3. Start the scan
Actual Results:
Memory Consumption spikes.
Only 1 processor core is in use.
Expected Results:
Memory consumption shouldn't spike
All available cores should be used, perhaps with a slightly higher nice level
