4. Consider an M/M/2 queue with arrival rate service rate . Find the mean delay in the system. Consider an M/M/1 queue with the same arrival rate and a single server that works twice as fast at the servers in part(a) namely 2 determine the mean delay and compare the results with part (a) as to which system is faster. a. b. 4.
