The most common way to use rsync is probably as such:

rsync -avr user@<source>:<source_dir> <dest_dir>

Resulting in 30-35MB/s depending on file sizes

This can be improved by using a more efficient, less secure encryption algorithm, disabling compression and telling the SSH client to disable some unneeded features that slow things down.

With the settings below I have achieved 100MB/s (at work between VMs) and over 300MB/s at home between SSD drives.


rsync -arv --numeric-ids --progress -e "ssh -T -c [email protected] -o Compression=no -x" user@<source>:<source_dir> <dest_dir>

If you want to delete files at the DST that have been deleted at the SRC (obviously use with caution:

rsync -arv --numeric-ids --progress -e "ssh -T -c [email protected] -o Compression=no -x" user@<source>:<source_dir> <dest_dir> --delete


  1. Because of the weak encryption used, it is not recommended for transferring files across hostile networks (such as the internet).
  2. There are scenarios where enabling compression can improve performance, i.e. if your network link is very slow and your files compress well.
  3. Don’t forget to forward your SSH keys to the host you’re going to run it on! (ssh-agent && ssh-add ((if it’s not already running)) ssh -A user@host)
  4. If [email protected] isn’t available for you due to using an old operating system, you can use aes128-ctr
