The frequency in ticks with which the lengths of the per-processor run queues
are examined to check that the differences exceed MAXIMBALANCE.
MAXCACHEWARM
Maximum number of ticks after which the cache is assumed to have turned cold.
MAXIMBALANCE
The maximum difference between two local run queues that is allowed.
Once this maximum is exceeded, load balancing requirements will dictate
putting affinitized LWPs on global run queue.
OVSTACK_PREEMPT
A boolean value that controls whether preemption is enabled while a kernel
LWP's (lightweight process's) stack is using the extension page.
When this tunable is set to ``0'' (the default), the
kernel will not preempt an LWP whose stack extends into the
extension page.
When set to ``1'', such preemption is enabled, thereby providing
enhanced real time response.
Enabling this feature can cause increased use of
the stack overflow memory, and
therefore, an increased value of OVSTACK_SIZE is recommended.
OVSTACK_PREEMPT and OVSTACK_SIZE are important when
you use drivers
that use more stack space and when you run real-time applications.
OVSTACK_SIZE
The quantity of memory (in kilobytes) set aside to handle stack overflow
conditions.
OVSTACK_PREEMPT and OVSTACK_SIZE are important when
you use drivers that use more stack space and when you run real-time
applications.
