After switching from Digikam V8.1 to V8.2 (both appimage) startup is very slow. At startup the function "Find new items" is evoked. In V8.1 (and previous versions) this process took less then a minute. In V8.2 it takes >40 minutes. When changing settings to "Miscellaneous Settings -> Fast Scan -> Checked" the scan is much faster. However, after adding new images to the collection and activating "Refresh" the images are not show for a long period. With this behaviour V8.2 is almost not usable. My configuration: Ubuntu 22.04 Digikam database on a local SSD. Image collection (>140k images) on a NAS. SQLite *** NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** STEPS TO REPRODUCE 1. Start Digikam 2. Process "Find new items" started automatically OBSERVED RESULT Process "Find new items" finished after >40 minutes EXPECTED RESULT Process "Find new items" should be finished after <=1 minute SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: Ubuntu 22.04 (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION
What's the Qt version used by digiKam ? 5 or 6 ? Go to Help Component info dialog for details. Gilles Caulier
Also did you use Snap package ? Can you run digiKam from a console after to enable debug trace in Setup/Miscs/System section ? Gilles Caulier

A test here shows no change in the scan time compared to a digiKam-8.0.0 AppImage version. I'll test it with an even larger network collection tonight. Do you use sidecars? Maik
Sorry Marc if I add you to this bug report. You have a slow network collection. Have you noticed a slowdown in scan time in digiKam-8.2.0? Maik

At least Darktable is writing to the sidecars, too.
An other user reports similar problems. Cf. following thread: https://discuss.pixls.us/t/digikam-8-2-scanning-for-new-entries-very-slow/40851/14 However, the user reports: "I’m not using a NAS, everything is on a local SSD in my case. So that can’t be the only reason."
Created attachment 164270 [details] Log file from appimage digiKam 8.2 I hope the attached log file helps.
I think I know the problem, files with sidecar keep getting rescanned due to a small change in digiKam-8.2.0. This was the change: https://invent.kde.org/graphics/digikam/-/commit/4cfbcbdc0c87bd958f4fa3d2715cefd88932c02b However, I forgot to make this change in the item scanner itself, so the modification date is not updated. As a test, you can change the option in the metadata settings for timestamp updating. The first start will be slow, then the following ones will be faster again. Depending on the time stamp update setting, the scanning speed has always been slightly different. Maik
Trying your proposal just now. It will take some time before I can report the results. Thanks a lot. DigiKam is a great tool.
The initial scan with the proposed setting took quite some time... However, after the scan in V8.2 works now as expected. Instead of >40 minutes its finished in 30 seconds. Thanks a lot.
Thanks for testing and reporting. I'll fix the problem tonight. Maik
Thank you, I appreciate that very much. Gerd

@Gerd Mann, if an AppImage with this change is available, I would be interested to know how it changed the scan time for you. The AppImage date must be greater than December 17, 2023. https://files.kde.org/digikam/ Maik
@Maik: I'll test and report results as soon as the new appimage is available. Gerd
@gerd, The new AppImage will be online in one hour at usual place. I start the build few minutes ago. Best Gilles Caulier
@Gilles: I just downloaded and tested the new appimage. With "Fast scan" and "Update file modification timestamp..." switched off the scan takes 43 seconds (collection size 140k images). That is faster than V8.1. It guess this resolves the issue in 8.2. My sincere thanks to you and Maik.
Great, thanks for the feedback. Gilles Caulier
I'm on Mac as my primary desktop these days and loved digikam on linux. I have been experiencing the exact same issue. Glad to hear it's fixed in 8.3 as I nearly gave up on Digikam (figuring it was a Mac specific issue). In my opinion this should be back ported to 8.2 or the whole 8.2 pulled (especially when the main page brags about how easy digikam is able to work with large libraries) but also because this gives new people trying out digikam a really bad impression. For anyone else coming here, I've managed to get an 8.3.0 version from: https://files.kde.org/digikam/
Sadly this has actually not fixed the problem for me. Calculating the time it's taken to get to 2%, I think I'm up for an hour or two. This is with fast scan on and using 8.3 10/1/24 7:08PM build. I take it since I'm on Mac I should open a new ticket rather than continue this one. Will do that.
