In the regard of java GC option -Xminf, it specifies the minimum percentage of heap that should be free after a garbage collection. If the free space falls below this amount, the JVM attempts to expand the heap.
However, as for the free percentage, i have a question here. How is that value calculated? Is it from 100%*freeHeap/AllocatedHeap or 100%*freeHeap/MaximumHeap? since it’s different, you know, please help me out.
Thanks in advance
Its rather freeHeap/AllocatedHeap. And it is not percentage but a decimal number between 0 and 1. Default value is 0.3.
