When to Change

When caches are large, or when the system is running a critical process or a set of processes that seem to suffer from excessive cache misses not caused by data access patterns.

Consider using the processor set capabilities available as of the Solaris 2.6 release or processor binding before changing this parameter. For more information, see psrset(1M) or pbind(1M).
