Tunable Base Page Size is a new feature introduced in update 3 to HP-UX 11i v3. The system administrator can now adjust the size of a base page used in managing system memory, by invoking the kctune command to change the tunable base pagesize and then rebooting the system. The larger base page sizes allow memory to be managed more efficiently, resulting in a decrease in kernel memory usage. This can also result in an increase in system performance for some workloads. This white paper describes this new feature, how the size of a base page affects the system, and how to use the new feature, including guidance on choosing a base page size for configuration.
