I have found that Darktable's performance depends far less on the overall number of *images* in the database than on the lexical properties of the *tags* in the database. I have one database with well over 50,000 images, with which I notice no performance problems, and another database with about 3,000 images, with which any operation involving tags is so slow as to render Darktable nearly unusable.
The difference, so far as I have been able to determine, is that the images in the smaller database each have a tag to identify the subject, resulting in an image/tag relation with a different structure to the usual. -- August Schwerdfeger aug...@schwerdfeger.name On Wed, Sep 21, 2016 at 1:46 PM, Frank J. <newslet...@fotodrachen.de> wrote: > Am 21.09.2016 um 20:00 schrieb Pascal Obry: > .. > > Strange since some of us have far more than 50k images.
