Anybody can reproduce this sluggishness?

Hey guys,
As it really bothers me in my workflow, I wonder, anyone can reproduce or clearly cannot reproduce this (need to be observed carefully) and mention the hardware and setup config.

My Hardware and setup:

  • Core i9 9900k, 2x GTX1060, 32MB ram
  • ~/.config/darktable on a NVME SSD with XFS
  • database integrity check done and o.k.
  • raw files on a classic HDD with XFS
  • find it in dt 2.6.2 and current master

Particularly I would appreciate the comments from the devs and also @plaven, @aadm, @garrett and @Claes. Indeed anybody else who can bring evidences :blush:
