: Hmmm, how did you do the measurement and how big of a file does it
:need?

: With a 122MByte file, it only does 2644Kbytes/sec. This is

2.6 MB/sec is what I would expect if you were running the test
over an ssh link on a fast cpu - the encryption eats a lot of cpu. But
a normal rcp or ftp or data transfer can easily do 9-10 MBytes/sec.

This is over 100BaseTX, *HALF* duplex running through a hub. 9.9 MBytes/sec.
(using 1 MByte = 1000 * 1000).
But if I use ssh instead, which I do only so I remember to turn off
the shell service in my inetd.conf that I just turned on a moment ago,
I am limited by apollo's poor PPro-200 and get:
test3:/root# ssh apollo -n "dd if=/images/swap/swap.209.157.86.6 bs=16k" > /dev/null
8192+0 records in
8192+0 records out
