Performance tuning and scaling

The design and implementation sections of the documentation contain plenty of advice in relation to performance. To ensure that relevant advice was heeded, see Designing applications and Application programming. If performance is ignored until the end of development, it might be impossible to fix without significant redesign, development effort, or both. This section focuses on basic advice on how to approach performance profiling of an FTM application and scaling it to meet the requirements. In most cases where high performance is expected the final deployment topology is complex with multiple threads, execution groups, LPARs, and even multiple geographic locations. Getting the best performance out of these types of deployment is not a trivial venture but if approached the right way need not be daunting.
