does the jvm allocate complete max heap size initially?
843829May 29 2008 — edited May 30 2008Does the JVM allocate the memory for the entire max heap size up front, or does it start with the specified minimum size and increase and grab more later if needed?
The reason this is being posted is because we have a number of jboss servers that are being run. Some don't require large heap sizes, others do. If we use the same large max heap size for all would all the memory get allocated up front, or possibly a smaller initialization portion?
