To participate in load management, each server or published
application must have a load evaluator assigned to it. The rules and their
settings determine how the load of a particular server or published application
For example, if you have a published application that uses a
significant percentage of a server’s memory and processing capabilities, you
can attach the Advanced load evaluator to every server hosting the application.
By doing so, XenApp distributes the available memory and processor demand
across the load-managed servers.
Each server or published application can have only one load
evaluator attached to it.
