There is simply no question that LR 2015.9 (and earlier) slows down with continued use during a session.


This is easy to replicate and demonstrate.


Lightroom starts up responsive and quick and, after a short while of working with images, begins to bog down: screen redraws, edits, crops etc all start to take longer and longer to accomplish.

Ultimately, previously instant tasks start taking 5 seconds or longer.


If you quit the app and restart the behavior resets to good response but then repeats as above.


Windows 10

Intel 6950X


2/Nvidia Titan Pascals 2/Nvidia GeForce 1080's  (tried with and without acceleration on)

All SSD or M.2 storage less than half capacity



100GB Cache (purged before testing)
