Understanding load balancing

Load balancing is a feature that allows client connection requests to be distributed among multiple Unified Broker instances that support the same Application Service. Load balancing is a NameServer option that comes installed with some products (for example, the WebSpeed Enterprise Transaction Server) or that you must install as an option with others (for example, the AppServer). If you have load balancing with your product, the NameServer assigns client connections to the appropriate Unified Broker instances based on weight factors that you specify.
If the weight factor that you specify for each Unified Broker instance is appropriate in relation to the others, the effect is to assign more connections to broker instances with greater resources, and thus to balance the connection load among all the instances. You can set the load-balancing weight factor for each Unified Broker instance in OpenEdge Management or OpenEdge Explorer or by editing the priorityWeight property in the file.
