Memory Pools
Java organizes its memory into pools, depending on the memory use. The main long-term heap memory is the Tenured memory. Other memory are optimizations of the Tenured memory. Eden is new, short-term memory. Survivor is long-lived memory.
CodeCache
The CodeCache is the JVM's non-heap memory pool containing the JNI compiled Java class code.
Eden
The Eden memory pool is used by the JVM for new, short-lived memory. Free memory in the Eden can be collected in fast garbage collections.
The Eden memory size is configured with -Xmn128m. In general, the JVM's defaults are fine.
