Limit number of simultaneous uploads
It's just taken me over an hour to sync my onedrive, because there were a large number of files added and each one sloooooowly uploaded simultaneously. Not only does this eat into my bandwidth for ages, but it means no single file became available on other devices. Allow us to set a limit of the number of simultaneous uploads, which will mean they upload more quickly before moving on to the next files. This, combined with the existing idea to prioritise uploads and/or pause individual file uploads would enhance the syncing experience significantly.

Having similar issues here - resolution for the moment is to move all the files out to a temporary non-sync'd directory and move them back in a couple at a time, this way they don't fail uploading (lots of large 10Gb files in parallel file frequently unless done one or two at a time)

For 7 very large files to simultaneously upload it takes ages. If you have an interruption for some reason, the uploads may need to start from the beginning. I moved them out of OneDrive and added them back one by one, after each upload finished. This is hardly a proper solution. The program itself should have a solution for this problem.
I have a need for this too. I am trying to upload several 600MB-1GB files and they keep restarting at some point, so none of them ever complete. If they were uploading only maybe 3 files at a time, i think it would finish. My upload speed is about 800Kbps on DSL.
