Thanks for the info.

Does that mean that KPA is slow for you even when no thumbnails are generated?

I had assumed that the background-jobs for thumbnail generation are 
essentially starving the GUI-thread. These background jobs are active for as 
long as the "LED-like" indicator in the status bar is flashing green.

You can click the indicator LED to get an overview of the running jobs and 
also for a pause/unpause button. If you pause background-jobs and use the 
annotation dialog on a subset of your images that already has thumbnails, do 
you still get the low performance?
