Exactly why it's hard to give a good answer.  It *really* depends on
what aspect you're interested in - I/O bandwidth, throughput, latency,
or other.  What I currently do at $DAYJOB is worry how fast I can get
a cluster of servers to flip blocks to and from disk to 40Gbit network
interfaces, and we've found a combo of iozone's and 'tar xf linux-2.6.32.tar.gz'
running at the same time is a good stand-in for our production workload.

Of course, your mileage will vary. :)
