Description Alessandro Lion 2021-09-28 09:46:53 UTC 
SUMMARY


STEPS TO REPRODUCE
1. Use the find duplicates on a whole album collection
2. click and while you wait 5 or 7 minutes, open the task manager
3. You can see low hard drive usage, zero network usage, only a little usage on the first core

OBSERVED RESULT
The function is not taking advantage of multicore processor which is almost a de-facto standard on modern computers.

EXPECTED RESULT
Would be great if rather than getting stuck 5 minutes or more for a task on a single core it will take 3 minutes by leveraging 2 or more cores.

SOFTWARE/OS VERSIONS
Windows: Windows 10 21H1
macOS: 
Linux/KDE Plasma: 
(available in About System)
KDE Plasma Version: 
KDE Frameworks Version: 
Qt Version: 

ADDITIONAL INFORMATION
Working on i7-1165g7 4core netbook with 16gb ram DDR4 and full SSD NVME storage I would not expect to see this click and wait behaviour on any software but windows updates.
