Rsync 3 builds the list of all directories incrementally, so there will be no delay at the beginning and rsync will be nicer to the disk cache. However, it does appear to refer to the list frequently, so if you have so many directories that the list grows too big to fit in memory, you may see poor performance due to swapping from that point of the run onward. This is just what I infer from the code, as I don't have experience with rsync on very large numbers of files. (My largest rsync job is backing up my computer, which is only about a million files.) The best advice I can give is to try it and see. -- Matt -- Please use reply-all for most replies to avoid omitting the mailing list.
