This setting allows you to specify an index representing the relative processing power of the current workstation. It is used with Dexterity’s load balancing feature.


DPSSystemIndex = index


index - An integer in the range of 1 to 1000 designating the relative processing power of the current workstation. Smaller numbers indicate better performance.


The system index is used in conjunction with the load factor assigned to each process group to calculate the processing load for the workstation. The processing load is the sum of the load factors for all processing groups multiplied by the system index.

For example, if three processes with respective load factors of 100, 200 and 50 exist in the processing queue of a DEC Alpha machine with a system index of 100, the machine's processing load would be calculated as follows:

(100 + 200 + 50) x 100 = 35,000

When load balancing is implemented for an application, the Distributed Process Manager evaluates the load on each available process server and assigns new processes to the process server with the lightest load.

The following chart lists the default system indexes that are assigned to the various machines that can run the Process Server:



System index

Intel 486


Intel Pentium


Intel Pentium II


The default values are only general estimates of processing power and do not take into account differences in performance from model to model within a single processor family. For example, you may want to assign a 133 MHz Pentium an index of 250 and a 300 Mhz Pentium an index of 150.
