FastScp

Fastscp work like the scp command, allowing you to transfer one or more files from one host to another. It uses the ssh service as a control channel. As such it is simple to install and use. It provides the following:

• Very fast file transfer, generally limited by the disk I/O.
  • Can sustain more than 100m/s on a gigabit network.
  • 2 gigabytes per second on loopback network, copying a file from /tmpfs to /dev/null
    (This shows the speed potential)
• Very simple installation. Nothing to configure. Just install the fastscp package on each host, and you can use it immediatly.
• No service to enable. It works on top of ssh to establish the session.
• Same syntax as the scp command
  • fastscp file1 user@host:/file_path
  • fastscp file1 file2 ... user@host:/some_dir
  • fastscp user@host:/file_path local_file_path
• Uses posix_fadvise to help the linux buffer cache. Especially useful for very large files.
