The attached screenshot explains most of it. CPU, outgoing network, and HDD usage all spike simultaneously at regular intervals when Rekordbox 6 is running. The waveforms slow and stutter every time one of these spikes occurs.
To me that looks like it's probably reporting usage info back to Pioneer - if it is, is there way to disable it? Also seems like a lot of data, I am NOT using cloud sync so I have no idea why Rekordbox would be sending out that much data.
