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.
