Scheduling

rechoose_interval

Description

Specifies the number of clock ticks before a process is deemed to have lost all affinity for the last CPU it ran on. After this interval expires, any CPU is considered a candidate for scheduling a thread. This parameter is relevant only for threads in the timesharing class. Real-time threads are scheduled on the first available CPU.

Data Type

Default

3

Range

0 to MAXINT

Dynamic?

Validation

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).

Commitment Level
