Requests pending                              Request arrival rate                 Processing time
Lrequest                                 =                       λrequest                     *                       Wrequest
LCPU                                   =                          λCPU                        *                       WCPU
Processes waiting                    Process phase arrival rate           Phase processing time
Where
All values are average, system in steady state. 
A         B   means A = αB,  for some constant α
We don't know α.
We know LCPU = load average
We know λrequest = request arrival rate.
