Initialization Code Runtime Reduction Effort

The recommended garbage collector for real-time applications is the copy collector. Or the treadmill collector, which is a variation of the copy collector.

All JVMs have the copy collector, but only for young objects. You can make it being used for all objects by increasing the young generation size. Set -Xmn<value> to the highest value the JVM allows, like "-Xmn511M -Xmx512M" and the copy collector will become the main GC. There are other parameters as well, but I can't find them right now.
