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.
