For an M/M/1 queueing system, we know that L =
(µ -). Suppose that

and µ are both doubled. How does L change? How does W change? How does W_Q
change? How does L_Q
change? (Remember the basic queueing relationships, including Little’s formula.)

In the M/M/s model, where µ is the service rate per server, explain why
µ is not the appropriate condition for steady state, but

sµ is.
