This is are long waiting times, up to 5 seconds until a scan is completed for
one image. Disabling the scanning does not help, he would be rescheduled in any
case. Modification date or file size have changed and need to be updated in the
DB. Writing to the SQLite DB is the time problem. The SQLite DB to put on an
SSD drive is strongly recommended. Here are a few measured values, writing of
one image information in the DB this include read new information from image
(images on HDD - EXT4):

SQLite: 180-270ms
internal MySQL: 40-70ms

SQLite: 30-60ms

Are the images on an NTFS partition? Is also here the SQLite DB?
