Which is faster SFTP or rsync?

rsync performs (2x) faster copying than sftp . sftp was achieving around 700 kbps while rsync transfers the data at a rate north of 1.4 Mbps.

Is there something faster than scp?

Rsync will obviously be faster than scp if the target already contains some of the source files, since rsync only copies the differences.

Is Sftp faster than rsync?

rsync performs (2x) faster copying than sftp . sftp was achieving around 700 kbps while rsync transfers the data at a rate north of 1.4 Mbps. I know that SFTP and SCP uses the same SSH connection for transferring files.

Why does rsync take so much time to transfer files?

If you are rsync thousands of small files in nested directories, it can simply be that rsync spends most of this time going into subdirs and finding all files. If time is not spend for browsing, the time might simply due to the addition of all the latencies starting each new file transfer.

Should I use rsync or rsync a file list?

Sticking with rsync, if you’re primarily mirroring a static set of files pass rsync a file list this way rsync won’t spend initially time polling your local filesystem to build a file list – saves a lot of time.

How often does rsync generate checksums?

If the files you are syncing do not change often, you can generate the checksums once per day in a cron job, and rsync will use the generated checksums. Rsync will still generate checksums for any new files or for any files that have a different modification time or size from when the checksum was created.

How much CPU usage when rsyncing from NAS to local disk?

In one test from a WD MyBook Live network disk, one or more rsyncs from the NAS on a Gigabit network towards 2 local USB disks would not copy more than 10MB/sec (CPU: 80\% usr, 20\% sys), after exporting over NFS and rsyncing locally from the NFS share to both disks I got a total of 45MB/sec (maxing out both USB2 disks) and little CPU usage.
