AIUI rsync is optimised to work over slow or high latency links and does parallel operations. Thus, while it may be doing checks it doesn't need to, these don't necessarily contribute to total time taken which will be dominated by data transfer times. Obviously this will depend on various factors - particularly the link speed and the performance of the two systems. If the stat operations happen in parallel with the data transfer, it may be that they don't affect overall time taken at all. -- Please use reply-all for most replies to avoid omitting the mailing list.
