This option sets the maximum heap size for the Java virtual machineVirtual Machine (JVM). XperienCentral uses memory for caching content from the database. A low value for this option can cause excessive garbage collection overhead and a lot database accesses. This option should be tuned based on the performance requirements of the application like number of concurrent users and the size of the content. If more memory is assigned to XperienCentral, more content can be cached in memory and the overhead of database access can be avoided.
Assigning more memory to the JVM will generally improve the performance. However, (excessive) swapping should be avoided as much as possible. Another drawback of a large heap is the fact that a full garbage collection will take more time. If the garbage collector uses a stop-the-world garbage collection policy, XperienCentral will be unresponsive for a longer period of time.
