- The frequency of file system sync operations.
- kernel_cage_enable=0
- Disable kernel cage.
- lgrp_mem_pset_aware=1
- default random policy applies only to lgroups with a process' processor set.
- Each JVM was run in its own processor set containing two cores (one whole chip).
- Each JVM was placed in the FX priority class with the priocntl command.
