Use the Service Binding tab to configure early or late binding for service objects.
When selected, this box specifies that services will be early bound. You should test the performance difference between early binding and late binding with your application. Early binding will definitely improve the speed of your application.
When selected, this box specifies that workers load the service object before timing the test. By choosing this option, the time needed to instantiate the service object is not included in the test duration. Preload Services has no effect if the Retain Service References box is not selected.
When selected, this box specifies that workers keep a reference to any service object as they are needed. The worker will only have to instantiate a service object the first time it’s used. After that first time, the worker uses its stored reference to the service to accomplish tasks.
