The load balancing threshold applies only to multiprocessor servers. Through extensive testing, Novell has determined the optimum threshold for load balancing across multiple processors—it addresses serious load imbalance while avoiding excessive thread migration. Without that play in the load balancing mechanism, threads would constantly move from one processor to another.
The optimum threshold has been preset by Novell and, in most cases, it provides the most efficient processor utilization. Although we strongly recommend that you do not change the threshold, this value is configurable.
IMPORTANT:Adjusting this threshold should be done only with considerable research and consultation. Experimenting with different threshold levels can best be done in an isolated test system. Do not experiment in a production environment. Remember that you can always return to the optimum setting.
To set the load balancing threshold:
In Novell Remote Manager, click the link under the heading in the navigation frame and then click the link.
Click the value link for the System Threshold parameter.
The page displays the current setting and the range of valid values. The default value is 1536.
To change the threshold setting, type a new value in the field and click .
For more information about the value ranges and default setting, see Multiprocessor Parameters
in the NW 6.5 SP8: Utilities Reference or the online help for the parameter in Novell Remote Manager.
To view CPU utilization by an NLM™ program in Novell Remote Manager, click the link under the Diagnose Server heading in the navigation frame, then click the link on the Profiling and Debug Information page.
