Four resource allocation
policies are defined out of the box. By default, the Equal_Per_Process policy is set, which
gives each process an equal share of CPU time. Only one resource allocation policy can
be active at any given time. This active policy is called the managing policy. In the WSRM

console, this policy is clearly identified by the string {Manage} that appears next to the
policy name. Following are the resource allocation policies:
?–? Equal_Per_Process Each running process gets its equal share of CPU cycles
(default).
?– Equal_Per_User Each user??™s processes get an equal share of CPU cycles.
?– Equal_Per_IISAppPool Each IIS application pool??™s worker process gets an
equal share of CPU cycles.
?–? Equal_Per_Session Each user-session??™s processes get an equal share of CPU
cycles (relates to Terminal Sessions).

You can control two types of resource allocation using WSRM: CPU and memory.
The general procedure for creating a policy is that you assign it a process matching criteria
that will tell the policy to which processes it applies, and then allocate a percentage
of your overall resources, whether CPU or memory, to those processes.
