tracks, visible on map, mysterious delay

[pebogufi]

Description

when opening "visible on map" the delay until i see a list is about 11 sec.
When i do a "wipe down" on the just opened new window, the delay is only 3-4 sec.
For me it looks like that the information for "visible on map" is already prepared, but will only be displayed if all other (not interesting) subdirectories are also scanned. My wiping does a refresh to show immediately.
I repeated measuring a lot of times.

This slow display happens only on my S10 (Samsung, Android 12, internal mem, storage/emulated/0/Android/media/net.osmand.plus).

On a other device the delay is about 3 sec without wipe. (Samsung Tab S5e, Android 10, SDcard, storage/xxxx-xxxx/Android/obb/net.osmand.plus).

Normally the S10 is MUCH faster than the Tab S5e.
The directory subtree is nearly the same on both devices.
Installed version on both devices

Using a "show visible tracks on map" with a smart folder is displayed IMMEDIATELY.
(see hint from @sonora months ago)

Scanning of all subfolders is nothing good for.
Just scan a subfolder if i open it.

Latest builds have become much better - try nightlies instead of release or beta.

I made the test with nightly of this morning.

First run could be very slow as whole database is being reindexed. Though later on it should start working fast

I know that there is some background processing immediately after start. I don't start measuring before the marker flags are visible.
Visibility of marker flags is a good indicator that the app is really ready to work (after start).
