CPU indicates the processing power of an appliance. CPU is measured in cycles. These cycles represent the time utilized to process a piece of data. Depending on the model of LoadMaster, the processor may have multiple cores. This allows multiple processes to be performed simultaneously. However, this does not automatically double the processing power of a unit. Processes must be specifically designed to utilize multiple cores. Certain processes in the LoadMaster are multi-threaded while others are not. This can put constraints on certain processes within the LoadMaster.
