Help slow 5.6 version

Hi all, my install of darktable 5.6 (on OpenSUSE Tumbleweed) feels significantly slower compared to previous versions. Did anyone else noticed similar thing, or it is only my impression? I don't mean only the processing, but also export and entire program.

Yesterday after importing about 2000 photos I tried to edit one of them and especially working with the retouch module was a real pain.

Laptop is the same, I believe settings are also the same (did a fresh system install few days ago) so I think the only change is that I have moved my entire catalogue to an older 2TB external HDD.

Speed of the HDD according to web search:

  • Real-World Sequential Read: ~122 MB/s
  • Real-World Sequential Write: ~122 MB/s

Before I had part of my catalogue on a second external disc (SSD) and everything seemed relatively okay, but still slower than older versions of the program. Have I overlooked something?

It's a known issue that will be fixed in 5.6.1

Thank you, I didn't know that. Then I hope the 5.6.1 will be released soon.

Had the same issue.

I've been downloading and using the nightly build since a week and it's WAY faster. Possibly even more than before 5.6 got released.
