Here are some results I have for data transfer speeds across a network
with a variety of hardware.  I'm afraid its in Dokuwiki internal text
format but it's fairly understandable I think (an advantage of
Dokuwiki):-


======Speed Tests======

These were done when I got a new 3Tb disk for backups to investigate the relative speeds
of copying files across the network.  All the tests were done __from__ //chris// to the 
named destination.

The //cp// column is for copying to an nfs mount, or in the case of //chris// to a local
filesystem.  Similarly for the //rsync to nfs// column for destination //chris// the copy
is to a local filesystem.

The USB 2.0 disk was in all cases my 750Gb eSata/USB drive with ext3 filesystem except for
one set of tests to raspberrypi with NTFS filesystem.

†† Results for the USB 2.0 drive on the //test// machine were **very** variable, by a factor of up to 3:1 between best and worst
cases, I've listed about the best speeds obtained.
