I did try -XX:+UseParNewGC, -XX:+UseConcMarkSweepGC, and -XX:+UseParallelGC, the first two both by themselves and together. -XX:+UseParNewGC shaved maybe 5 seconds off the test run time. -XX:+UseConcMarkSweepGC actually made my test about 10 seconds slower, and -XX:+UseParNewGC didn't make much difference.
My sense was that some of those were aimed at multiprocessor systems with larger numbers of processors than the 2 in each of my machines. I'd easily believe that if I had 4 or 8 or 16 CPUs, I'd see a lot more benefit. I will check out those profilers. Thanks for answering my newbie questions -- poking and prodding the JVM is something I've never had a need to learn much about until now.
