Transfer of files from one server to existing server using SCP and its performance
SCP (Secure Copy)
scp allows files to be copied to, from, or between different hosts. It uses ssh for data transfer and provides the same authentication and same level of security as ssh.
$ scp username@remotehost:sample.txt /some/local/directory
SCP Performance improvement:
By default scp uses the Triple-DES cipher to encrypt the data being sent. Using the Blowfish cipher has been shown to increase speed. This can be done by using option -c blowfish in the command line.
$ scp -c blowfish <<filename>> username@remotehost:~
$ scp -c blowfish -C <<filename>> username@remotehost:~
Before executing the above command, make sure about folder permissions.
Try it and explore yourself..!!

It is often suggested that the -C option for compression should also be used to increase speed. The effect of compression, however, will only increase speed if your connection is very slow. Otherwise it may just be adding extra burden to the CPU.
An example of using blowfish and compression:
