Sometimes I have a local and the NAS location of my mediafiles in the Archive (by mistake, or when migrating).
In MM4 it takes a second, to remove an unwanted location.
In MM5 every single File is removed from Library, one after the other.
That takes about 4 hours for 40.000 track. Is there an faster way?

Re: Deleting a node in "Location" runs extremely slowly
No, I don't.
Because the DB was migrated from an old "orphaned" MM4-installation (last MM4 version is portable), I just make a new clean installation.
Same results.
Deleting a node from Library (not from disk) in Location takes much more time than scanning for new files.

Re: Deleting a node in "Location" runs extremely slowly
Hi, testing this and seems fast for me.
I remember an issue like this when the particular DB was missing some DB indexes.
In that case the menu Maintain Library > 'Rebuild database' option re-creates the DB indexes (if that's the issue)
But please backup your current MM5.DB at first or open eSupport ticket and share link to your database (compressed %APPDATA%\MediaMonkey5\MM5.DB file)

Re: Deleting a node in "Location" runs extremely slowly
Thanks for that hint.... but DB-reorg doesn't have any effect.
Removing is slow on 3 different PCs (Win 11) with clean install, fresh scanned Media folders, rebuild DBs...
DB and/or Mediafiles local and/or on NAS...
Same behaviour.
Scanning an new local folder with 1472 Files takes 2:11 min.
Removing takes 6:00 min (writing to the disk with the DB: 1600 B/s)
(I'll try an installed MM5 instead of portable)
EDIT: No change
EDIT: Same problem with Win 10 pro
EDIT: Same with official release MM 5.0.2.2531

Then please catch this in debug log and attach to eSupport ticket, see item 4b here: https://www.mediamonkey.com/forum/viewt ... 30&t=86643
Re: Deleting a node in "Location" runs extremely slowly
A lot of thanks to Ludek, who helped me patiently in discovering the reason.
My DB resides on the NAS for common use in different rooms.
The difference between MM4 and MM5 is the way, data are written to the DB.
MM4 hold them in Memory for a while, MM5 write them at once.
Therefore MM4 needs only 4 journal-files on the NAS for deleting 280 records. MM5 needs 280.
That traffic reduces the speed extremely.
In MM5 it's better to use a local DB.
