I’ve got some real performance issues with two instances of linux Mint 22.3, though the main working laptop is where I’m having the distinct problem (v3.9.7.60031). I’d already had the source folder filled with content and found everything was been downloaded although the content was already present. After stopping/starting the process and limiting the folders to be synced things settled down after wasting a lot of bandwidth. Looking at the actions there are numerous files unnecessarily downloaded. I’ve recently added a new sub subdirectory which has not been added at all even though the top level shows everything is synced, In the end I directly uploaded it to Dropbox via the web and then it was downloaded.I’ve been consisting using the 2 way sync to the folder.
