Figure 1.9: MetaFrame XP load evaluators.

Table 1.4 lists the available load-balancing rules and briefly explains what they do. I’ll discuss

load balancing in more detail in Chapter 5.

Load Evaluator Description

Application User Load

This rule limits the number of instances of a

particular application that can run on the server in

question. Use this rule to limit usage of resource-

intensive applications.

Context Switches

Win2K can run in either of two modes: user mode

and kernel mode. All processes are protected from

each other in user mode; in kernel mode, all

processes use the same memory space. Every

time Win2K changes processing from one mode to

another is called a context switch. You can limit the

number of connections to a terminal server

according to the number of context switches it’s

doing each second.
