Is /jdata/BackgroundMaps preferred over /VS Data/BackgroundMaps?
The "VS Data" folder was where all project data was stored with WinCE OS. Now with Linux it is stored in the the "jdata" folder and the "VS Data" will no longer be used.
My download speed is 23.6 Mbps and upload speed is 2.4 Mbps. Maybe you just had many projects stored on your LS. I also used an ethernet connection rather that WiFi.
