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.
WARNING: 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.
Use this procedure to set the load balancing threshold.
In MONITOR's Available Options, select Server Parameters > Multiprocessor.
The multiprocessor parameters appear in the upper window.
Highlight the System Threshold field.
The pop-up window displays the current setting and the range of valid values. The optimum value is 1536.
To change the threshold setting, press Enter and type a new value in the field.
To exit MONITOR, press Alt + F10.
