Notes:

  • protocol overheads will reduce these; ftp is typically a light protocol, something like scp is extremely heavy (plus has a hit on the CPUs on both ends of the transfer, with may also reduce throughput)

This is a collection of techical information, much of it learned the hard way. Consider it a lab book or a /info directory. I doubt much of it will be of use to anyone else.
