Following are the results of transferring a single file via rsync from the mounts of the specified versions. Different files were transferred so the size may vary a little.
Mount Command:

Another observation is that if more than one process is accessing the same file in the mount2, it bring all the existing transfers of that file to a crawl. (~40 MB/s to ~5 MB/s)
