My promised update since 3 days ago…
Files to sync is now 287,396. That’s an average of 8000 files per day, roughly. With my remaining number of files to sync, this will take another 36 days to sync my (currently) 200+GB of data from Drive to my machine. Another whole month?!
Increasing the concurrency from 2 to 8 files would help a lot! So much time is wasted in queuing the files internally, it seems.
