+ All systems were dual quad core Intel(R) Xeon(R) CPUs running at 2.50GHz. Eight cores were
available however as noted below Linux's processor affinity feature was used to limit CPU
availability to the JVM. In the tests below I use 1, 2, or 4 CPUs.
  
  All systems had 16gig memory available, however unless specifically noted the JVM's -Xmx
option was used to limit the size of the JVM heap to 512m.
