Why does the first scan take so long to finish?

Answer / Solution

The first scan of SpaceObServer always takes longer than the subsequent scans , since the whole database structure has to be build and the complete file system information is collected during the initial scan. Update scans only collect the file system changes since the last scan. The speed of update scans basically depends on the number of file system changes, the number of changed files and the database size (amount of data that has already been collected into the database).
