About the AppLogic Performance Value
The AppLogic Performance value represents the performance of the AppLogic object running on a Netscape Application Server. This value is calculated for each AppLogic object participating in load balancing. This allows load balancing to occur on an AppLogic object basis and increases distribution.

The AppLogic Performance value is composed of five AppLogic criteria. The load balancing service compares Netscape Application Servers based on the weight factor you assign for each AppLogic criterion. The server with the highest total value is chosen to process requests for that AppLogic object. The AppLogic Performance criteria are described in the following table:


AppLogic Performance Criteria	Description
Server Load	The value calculated for all Server Load criteria. For more information about this value, see "About the Server Load Value."
Cached Results Available	Whether the results of the AppLogic object are cached. A user's request is typically processed faster when the AppLogic object's results are cached.
Lowest Average Execution Time	The time with which an AppLogic object takes to run on each Netscape Application Server.
Most Recently Executed	The server that most recently ran an AppLogic object. The system on which the server is running might have cached AppLogic data, resulting in a faster execution time if that object were to be run again soon.
Fewest Executions	The number of times the AppLogic object ran on a Netscape Application Server. The goal of load balancing is to equally distribute requests among all servers in the enterprise. Therefore, the server that has run the AppLogic object the least number of times is most preferred.

Each AppLogic criterion is multiplied with a weight factor you set. Each value is then averaged to determine the final AppLogic Performance value. The final value is used by the load balancing service to determine which Netscape Application Server is best able to handle new users' requests.

For more information about adjusting the AppLogic criteria weight factors, see "Adjusting Weight Factors for AppLogic Performance Criteria."
