Performance considerations for logical partitions
You can manage and enhance the performance of logical partitions so that your system uses its resources in the most efficient manner.
You can manage and enhance the performance of a AIX® logical partition by configuring the AIX operating system.
Managing IBM® i performance ensures that your managed system is efficiently using resources and that your managed system provides the best possible services to you and to your business. Moreover, effective performance management can help you quickly respond to changes in your managed system and can save on expenses by postponing costly upgrades and service fees.
- Adjusting the Active Memory Expansion configuration to improve performance
You can run the Active Memory™ Expansion planning tool to generate performance statistics for an AIX logical partition that uses Active Memory Expansion. Then, you can change the Active Memory Expansion factor, the memory assignment, or the processor assignment of the logical partition to improve its performance. - Performance considerations for shared memory partitions
You can learn about performance factors (such as shared memory overcommitment) that influence the performance of a logical partition that uses shared memory (hereafter referred to as a shared memory partition). You can also use shared memory statistics to help you determine how to adjust the configuration of a shared memory partition to improve its performance. - Adjusting the shared memory configuration to improve performance
You can use the Hardware Management Console (HMC) to adjust the configuration of your shared memory environment to improve its performance. For example, you can change the I/O entitled memory or the memory weight that is assigned to a logical partition that uses shared memory (hereafter referred to as a shared memory partition.)
