Worker processes and applications pools can be associated with specific CPU's to take advantage of more frequent CPU cache (L1 or L2) hits. This processor affinity allows you to control the processors when known applications place demands on system resources. For example, if your requirements are such that the hosted application needs dedicated processors, then after enabling dedicated application mode, you can create one application pool with four worker processes that are associated to CPU's 0-3. Processor affinity only pertains to multi-processor computers as it is not designed to work remotely.
