A garbage collector (GC) can consume up a considerable amount of your resources. The Java Hotspot (TM) virtual machine provides a multitude of parameters to tune a GC (among several other components) for a specific application and its load. We have explored these optimizations in detail in cooperation with dynatrace Austria and have published it in a paper at the International Conference on Performance Engineering.

You can download our framework here and try it on your own application. Please look into the README file for a detailed description.
