Waoo. Simple. Beautiful. Successfully installed and tested sync on 2 Synology NAS DS712+ and DS713+ (both x86_64). Special "sync synology build 1.0.116". Worked like a charm between 2 optical fiber connections, each capable of uploading @50mb/s As I ran merly 5.5MB/s, eg. around 40 mb/s, i guess the protoocol is working great Continue testing but this sounds very promising.
