[Bug 310050] New: Slow performance after canceling a large duplicate image search.

            Bug ID: 310050
          Severity: critical
           Version: 2.9.0
          Priority: NOR
          Assignee: [hidden email]
           Summary: Slow performance after canceling a large duplicate
                    image search.
    Classification: Unclassified
                OS: Linux
          Reporter: [hidden email]
          Hardware: Gentoo Packages
            Status: UNCONFIRMED
         Component: Searches
           Product: digikam

Database Driver : QMYSQL
Slow performance after canceling a large duplicate image search, even after
restarting digikam constantly,
doing a right click on a image takes a long time including most other
functions. The only way around this is to delete
$user/.kde4/share/config/digikamrc and re-add the MYSQL database & image
directories... then performance is fully restored. Also I would like to see
searches split into multiple threads as it takes forever to do searches in
large databases... perhaps adding a number of threads to options would be
great.

Reproducible: Always

Steps to Reproduce:
1. Do a duplicate file search on a large database 100k or more files.
2. Cancel Duplicate File search in progress.
3. Performance grinds to a halt.
Actual Results:  
Very slow performance selecting images, right clicking etc..

Expected Results:  
Same performance as when the database was first created.

Fuzzy & Duplicate Image search is slow please add options to add more threads
and fix this bug. - Thanks

I thought I would also add after the search is canceled... the duplicate search
boxed is greyed out and you can do no more searches until digikam is restarted.
However performance is still sluggish until digikamrc is deleted and
database/image directory is re-added.
