In reality, this report is larger but I chopped it down a bit for
brevity. autonuma beats schednuma *heavily* on this benchmark both in
terms of average operations per numa node and overall throughput.

It is impressive report!

Could you like to share the what JVM and options are you using in the
testing, and based on which kinds of platform?

Oracle JVM version "1.7.0_07"
Java(TM) SE Runtime Environment (build 1.7.0_07-b10)
Java HotSpot(TM) 64-Bit Server VM (build 23.3-b01, mixed mode)

4 JVMs were run, one for each node.

JVM switch specified was -Xmx12901m so it would consume roughly 80% of
memory overall.

Machine is x86-64 4-node, 64G of RAM, CPUs are E7-4807, 48 cores in
total with HT enabled.
