I am using Linux V 3.9.6.60027 and I have a 1TB fibre link. My syncing with OneDrive 365 is very slow. There is not a huge amount of files, with some fairly large .mp4. If I copy files from the web client, it is almost instantaneous, with the whole being downloaded in less than a minute. However, with Insync it is taking 2-3 days. Why is this?
