I have a few large files that I need to copy from one Linux machine to about 20 other Linux machines, all on the same LAN as quickly as is feasible. What tools/methods would be best for copying these files, noting that this is not going to be a one-time copy. These machines will never be connected to the Internet, and security is not an issue.
The reason for my asking this is because (as I understand it) we are currently using
scp in serial to copy the files to each of the machines and I have been informed that this is "too slow" and a faster alternative is being sought. According to what I have been told, attempting to parallelize the
scp calls simply slows it down further due to hard drive seeks.
