In Java, the default and maximum heap size are allocated based on this â ergonomics algorithm. Heap sizes. Initial heap size of 1/64 of physical memory up to 1Gbyte. Maximum heap size of 1/4 of physical memory up to 1Gbyte.
The JVM uses memory in a number of different ways. The primary, but not singular, use of memory is in the heap. Outside of the heap memory is also consumed in Metaspace, and the stack. Java Heap - The heap is where your Class instantiations or âObjectsâ are stored. Instance variables are stored in Objects. When discussing Java memory and optimization we most often discuss the heap because we have the most control over it and it is where Garbage Collection (and GC optimizations) take place. Heap size is controlled by the -Xms and -Xmx JVM flags.
