Resource management

AIX® provides tunable components to manage the resources that have the most effect on system performance.

For specific tuning recommendations see the following:

Microprocessor performance.
Memory performance.
Logical volume and disk I/O performance.
Network performance.
NFS performance.

Processor scheduler performance
There are several performance-related issues to consider regarding the processor scheduler.
Virtual Memory Manager performance
The virtual address space is partitioned into segments. A segment is a 256 MB, contiguous portion of the virtual-memory address space into which a data object can be mapped.
Fixed-disk storage management performance
The operating system uses a hierarchy of structures to manage fixed-disk storage.
Support for pinned memory
AIX enables memory pages to be maintained in real memory all the time. This mechanism is called pinning memory.
