Which one of the following counters in Windows NT performance monitor is most
helpful in moderating the workload on a single processor as it is executing threads?

A.
PROCESSOR: elapsed time

B.
MEMORY: pages/sec

C.
PROCESSOR: %processor time

D.
PHYSICAL DISK: %disk time

Explanation:
By checking the processor time, we can see how much cpu resources
are actually being used. Processor time will tell us how much cpu is being demanded
by the process. He higher the processor time,
Incorrect Answers:
A: Processor elapsed time does not give a good picture of cpu resources consumed.Elapsed time
indicates how long it takes for a program to run, which is dependent onwhat else is running in the
system, and system priorities. Elapsed time provides anoverall throughput value of how long it
takes for the job to run, clock time. Elapsed timeis dependent and controlled by the workload mix.
B: in a single processor system, with multiple threads, cpu contention becomes thebottleneck, and
it is CPU and not memory that needs to be monitored.
D: in a single processor system, with multiple threads, cpu contention becomes thebottleneck, and
it is CPU and not disk performance that needs to be monitored.
