fast internet file copy (?)

[Web Dove]

We have two vax/750's running 4.2bsd on the same internet wire.  Both
have interlan NI1010 network interfaces.  What is the fastest way of
getting a 250,000 byte file from one to the other with this medium?

FTP rarely does better than 20kbytes/sec.  Is there a way (perhaps
using raw sockets or some other special xfer protocol) to get close to
the megabit per second speed of the wire?
