Pro DJ Link with CDJ3000

Hi,

CDJ3000's give me loading issues. I always use Pro DJ link with a backup SSD drive in one of 3 players. CDJ2000NXS2 where fine but CDJ3000's are either fast or extremely slow. Like 1 minute slow. Last weekend i even needed to shut down Rekordbox completely because it kept saying "loading" and only the live player kept on playing. The weird thing is that when the issue occurs, it doesn't help loading the track in another player. They end up in the same freeze. Loading tracks from the external SSD is impossible during these freezes. 

The problems occur with different brands of network switches and in settings where the cdj2000nxs2's work fine. I changed my riders back to 2000's for that reason.
