14 Consider the following two queuing systems:

System 1 An M/M/1 system with arrival rate l and service rate 3m.

System 2 An M/M/3 system with arrival rate l and each server working at rate m.

Without doing extensive calculations, which system will have the smaller Wand L? (Hint: Write down the birth–death parameters for each system. Then determine which system is more efficient.)
