Very laggy on Android mobile app when scrolling on default photos view

[maltokyo]

The bug

When scrolling on Google photos, the scrolling is extremely smooth even when scrolling too fast for full thumbnails to load. On Immich this is very laggy. Granted I have 100k photos, so not sure if that's the issue but it should still work. Attached a screen recording of me scrolling at a constant speed, and the laggy scrolling is clearly visible.

@maltokyo how many albums do you have? Did you start scrolling right away when you first open the app?

The stuttering is due to the albums sync mechanism compete with the UI thread, after the albums sync finished, it will be smoother.

Regardless, we have plan to optimize this process for a better user experience

[maltokyo]

Thank you for the replies. Yes I used a script to make albums from about 1000 folders. So, many albums. But immich has been installed for weeks. So I thought it maybe has had enough time to scroll correctly. Thanks for the news on optimizing this.

@maltokyo the sync here check for the diff with the server, adding and removing assets on the mobile...etc, basically expensive operations that can be taxing for the client, and it runs when opening the app and after some certain actions.

[maltokyo]

Thank you. Everything is in sync. I haven't added any photos for many weeks. Nothing is there to sync.

@maltokyo maybe a better wording from is the operation of figuring out what to sync is taxing and competing with UI thread

[maltokyo]

@alextran1502 ok, is there anything I can do to get more data on this on my side, in order to find out what is causing the issue? Some way to get logs (and which ones?) from mobile or server, please let me know. Any way I can assist, I'm willing to of course.

[alextran1502]

@maltokyo thanks for the offer, we already known the bottle neck and have plans to word toward improving it in the near future

[maltokyo]

Understood. Thanks a lot. Apart from this, everything is absolutely amazing.
