I noticed a difference between running

    touch testfile{00001..10000}

a first time and repeating it. Dolphin worked a little harder but it was still
just a second or so of high CPU.

Baloo spent a while catching up with changes and baloo_file_extractor had a
look at the "touched" files (in batches of 40). Nothing excessive though...

Could there be an issue with large numbers of thumbnails? (How big is
.cache/thumbnails/normal?)
