Slow library updates using MySql and clients with different operating systems



I’m using mySql shared video libraries and have Kodi installed on my nvidia shield and windows laptop.  If I only update the library from the shield, scans go quickly.  But, if I then do an update on the windows machine, the scan is much slower.  Subsequent library updates on windows go quickly.  If I then go back and do an update on the shield, it’s slow again.  Subsequent updates on the shield are quick.

I reviewed the debug log on a slow scan and find many entries like this:

Code:
2024-05-21 21:42:00.185 T:18564   debug <general>: VideoInfoScanner: Rescanning dir 'smb://nas.home/kids videos/Movies/Shrek (2001)/' due to change (0e1f090b967e89a6dfb9924f435040a8 != 5be2327d846c4035fbe27fa7aad0f864)
2024-05-21 21:42:00.728 T:18564   debug <general>: Mysql execute: update path set strHash="5be2327d846c4035fbe27fa7aad0f864" where idPath=70

It looks like the strHash value is changing and requires updating.  Is that why the scans are slow?  Is this expected behavior?  Are shared library updates expected to be performed on only one OS?

BTW, I’m using the The Movie Database Python and TMDb TV Shows providers on both machines.
