Minimize Java heap measurement by reducing the values in the parameters MaxHeapFreeRatio (default price is 70%) and MinHeapFreeRatio (default look here worth is 40%) With all the command-line alternatives -XX:MaxHeapFreeRatio and -XX:MinHeapFreeRatio. Decreasing MaxHeapFreeRatio to as low as ten% and MinHeapFreeRatio to five% has properly minimized the heap measurement without having a lot of functionality regression; however, effects may well range significantly based on your application.
