Collection brwosing is heavy and slow!

How many tracks in your collection and where is the collection stored (internal / external), and if external, how is the drive connected?

I have about 80000 Tracks stored in my internal system drive because rekordbox can't see any external drives or partitions but the point is that in other programs exactly the same collection i use and the browsing is smooth. Here you don't have to be in the collection section to face heavy response but in each folder or playlist seperately. Thank you very much.

select all tracks and right click "Add new analysis data" in rekordbox
