Lower the Java heap dimension by lowering the values from the parameters MaxHeapFreeRatio (default price is 70%) and MinHeapFreeRatio (default value is 40%) Using the command-line solutions -XX:MaxHeapFreeRatio and -XX:MinHeapFreeRatio. Lowering MaxHeapFreeRatio to as low as ten% and MinHeapFreeRatio to five% has correctly lessened the heap measurement without having excessive effectiveness regression; nonetheless, success may well this content change considerably based on your software.
