I don't think so. You need to run your tasks on your own hardware and network to see where the bottlenecks are. If the task is CPU-bound, turn off or lower compression (-z1) and see if that improves the total wall-clock transfer time. If the task is network bound, try turning on compression, or tweaking --sockopts to increase your TCP send and receive windows on both ends of the connection. If the taks is disk-bound, try using --inplace, -W, or any other options which prevent extra file reads and writes. -- RPM -- Please use reply-all for most replies to avoid omitting the mailing list.
