I am running rsync on a small linux server to synchronize files in one directory and its subdirectories from Windows (using sshd from Cygwin) to this server for backup purposes. The directory contains almost 1 TB of images and videos in about 160k files on a slow disk (Seagate Archive 8TB with SMR) with NTFS.
Even if there are no changes and whith whole file transfers rsync takes about 45 minutes to come to this conclusion. I am using the following command line on the linux server: rsync -avx --stats --whole-file --no-perms --no-owner --no-group <user>@<server>:<source directory> <local destination directory> As rsync was only transferring a small number of bytes and gave no clue to the cause for being so slow and as rsync should only need filenames, dates and sizes I did a "ls -lR|wc" on both systems. On the linux server this took about 1 minute (only slightly faster magnetic disk, empty read cache at start) and doing the same on cygwin took almost as long as rsync (over 40 minutes). Using Windows Explorer (after a reboot to guarantee that the cache is empty) to get the total number of files and the total size took only a few seconds. Reading all file sizes with Treesize also took less than one minute. As ls -lR needs the same information I would have expected it to take the same time. Runnin "ls -lR" a second time on Cygwin is fast as lightning as it only takes less than 30s. Is there any way to get ls -lR or better rsync as fast as listing the directory with Windows tools?
