            Bug ID: 310050
          Severity: critical
           Version: 2.9.0
          Priority: NOR
          Assignee: digikam-devel at kde.org
           Summary: Slow performance after canceling a large duplicate
                    image search.
    Classification: Unclassified
                OS: Linux
          Reporter: zeronullity at comcast.net
          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
