[clue] Link speed test

[David L. Willson]

Here are the commands I use to test sustained read and write throughput.

# write speed, presumes device to test is exclusively mounted at /mnt (or that other sources of I/O are inconseqential)
dd if=/dev/zero of=/mnt/test.dd bs=4M count=256

# read speed, same presumptions
dd if=/mnt/test.dd of=/dev/null

Both commands output a summary of I/O speeds when they complete.

These commands to work equally well to test network throughput, but network throughput is the slowest of the network and any involved storage devices, minus a bit for management. I'll be trying netcat and netperf as time allows.

This is a good time for a r3VOLution.
