I can reproduce the Decade node on 2415, added as: https://www.ventismedia.com/mantis/view.php?id=18023

However Location isn't slow on 2415, have you tried a optimize database: https://www.mediamonkey.com/wiki/WebHel ... aintenance

When trying to view information in the 'Year' node in the navigation view of any media types, when in default view, each 'branch' of the tree takes many seconds to load with the information not being cached so each access results in a new very slow reload of information. This was instantaneous in MM4

This does not show up in the debug logger

MM 5.0.0.2338 - Windows 10 Pro 64Bit 20H2

In the Navigation View the navigating down the tree in the Video/Location View takes an excessive amount of time for each step of the process when the screens are in default view. The same occurs under the music node.

Also - the information does not seem to be being cached so each time it's accessed it takes an age to get to a folder location - many seconds if not minutes.

This is not being reported via the debug log file.
