Performance - Managing Workload (Magic xpa 3.x)

Magic xpa applications are CPU intensive. Performance tuning of a CPU intensive application on an IBM i platform has always been a complex issue due to the lack of CPU control tools in OS/400 and OS i. CPU intensive applications allocate the maximum number of available CPU resources during runtime, which leads to a loss of performance in other applications. As of OS i 6.1, it is possible to set up a better application isolation at the CPU level. It is applicable for multi-core systems where it is possible to limit the processing requirements of a workload to a subset of processor cores. For more information, click here.
