benchmark results on my $75/month 5 node cluster :)

Here is an updated 2 hour graph of the same "X-Small" 5-node cluster,
after having performed all the Linux tuning steps I had missed first
time around. Also added ntpd service to all nodes. Looks like slightly
better throughput & latency, but a much cleaner graph overall, and it
should "burst" much better:
Here is the same cluster rebooted as "Medium" Azure VMs, same
benchmark settings except: 8 workers, shorter duration. Not sure why
it has errors, yet:
Anyways- back to work for me!!!
