Indexing folders of images on an Apple Mac

Simple question : does manual indexing of folders of images complete on your Apple computer?

On my machine my images are stored in sub folders with one per shoot date. When I attempt to index my collection the process never ends and does not appear to do anything.

However, if I place a large number of images into a single folder and then index the folder the process seems to work with CPU usage increasing, fans running and the indexing finishing.

I’ve run several tests for this and found that

  • Different versions of DPL take different amounts of time to complete.
    Times varied between 30 minutes and 90 minutes for a structure of folders
    that is at least 3 levels deep (approx. 25’000 files on levels 4 or deeper)
  • Indexing times were shorter when I deleted database files before starting
  • Approximate database file size, after indexing
    DPL2: 340 MB
    DPL3: 370 MB
    DPL4: 70 MB

This is how I did it:

  1. Point DPL to an empty folder
  2. Quit DPL
  3. Delete database and cache files
  4. Prevent the Mac from sleeping
  5. Open DPL and start indexing

We can see that DPL4 creates a lighter database than DPL versions 2 and 3, probably due to a new database design.
