6.6 Using large page sizes
AIX provides multiple page sizes to help increase performance of memory intensive applications. Because all applications running on WAS with a large heap will realize a benefit from using larger page sizes, their use is recommended.
This section explains how to use the large page sizes available on AIX. For an in-depth explanation of the multiple page sizes offered in AIX and how to use them, refer to the white paper Guide to Multiple Page Size Support on AIX 5L Version 5.3.
