  • My advice on JVM heap tuning, keep your fingers off the knobs! – On startup, the 1.6 JVM does a survey of the environment in which it is executing and uses that information to determine if it should behave as a server or a client JVM. This choice affects, the number of GC helper threads, the sizes of the various spaces with-in the heap and a whole wrath of other configuration values. But configuration doesn't stop here. Instead dynamic profiling directed by GC ergonomics is used to further refine how much heap is allocated, how it is to be proportioned to if we need to change from the less efficient throughput focused collector to the more efficient implementations. Now here is a take away, the more switches you set, the more parameters you fix, the less options ergonomics has to dynamically adjust to the situation on the ground (or in the JVM as it may be). Short story, the less you fiddle with, the better things will be for you in the long run.
