This chapter focuses on performance tuning concepts in the Java stack, such as memory allocation in the Java Virtual Machine (JVM); the garbage collection process in the JVM and its relationship to performance tuning; and scaling Java stack–based SAP applications by adding server nodes, threads, and, if needed, application servers. We will cover tasks such as configuring heap size and different memory areas using tools such as the configuration tool. We will also discuss common SAP Java performance issues, and toward the end of the chapter, specific examples will be provided for improving NetWeaver portal performance.
