Does anyone have experience with Syncthing in high-latency connection scenarios, for example across continents? I need to bring and keep up to date tens of TBs between a couple of servers very far apart (~200ms ping). Almost everything I've tried transfers at a fraction of the speeds possible. The exception is Rclone where I'm able to properly saturate the connection.
Garage claims performance across long distances (up to 200ms per their front page).
It's not a POSIX file system. Instead it's more like S3. You could put something in front of it, perhaps, to make it POSIX.
