The fastest way to transfer files between two neighboring computers

I have two neighboring computers, both of which work with the latest version of Ubuntu. Both computers have:

  • Multiple USB 2.0 Ports
  • RJ-45 connection
  • 5400RPM hard drive
  • Express Card Slot
  • PCMCIA Type II

I want to transfer as much data as possible over a given period of time.

  • What is the fastest physical medium for transferring data between two computers without sharing hard drives?

  • What is the fastest protocol (not necessarily used based on TCP / IP) for high entropy data transfer? If it is TCP / IP, what should be optimized for optimal performance?
