Selecting ‘Music’ results in 10-15 minute wait for library list to populate

Hello,

I currently have Kodi 16 installed on a Raspberry Pi 3. On my server I have a rather large collection of music, easily 10-20k songs, that I point my Kodi too. Whenever I turn on the Pi and select ‘Music’ I have to wait a good 10 or 15 minutes before the songs populate the list. After that they play fine, but the list population takes awhile. Are there any settings that can speed this up? Correct me if I am wrong, but shouldn’t Kodi keep this list after the initial population of it, in a local database? If that is true, then is this just the result of having a large database that takes awhile for the Pi3 to load, even locally?
