The first one is CPU utilization. In general, a healthy system's CPU utilization should range between 8% and 40% most of the time. There will, of course, be times when utilization will spike up to 80, 90, or even 100%. This may occur when you launch a new application on the desktop. This isn't a problem as long as it is temporary. The CPU utilization should quickly drop back down to the acceptable range. In the example shown here, the CPU utilization remains within the acceptable range most of the time, with just a few occasional spikes. However, if the CPU utilization consistently remains above 40 to 50%, then the processor is being overutilized and could easily become a bottleneck. If the CPU utilization consistently remains above 70 to 80%, then the CPU has definitely become a bottleneck that needs to be addressed. CPU Overutilization Issues 1:59-3:00 To address an overutilized CPU, you can unload unnecessary applications and services. Running too many processes on the CPU will result in overutilization. Likewise, running a CPU intensive application can also result in overutilization. You can upgrade the system to use a faster CPU. This allows the system to process more instructions within a given time period. You can upgrade the system to use a CPU with additional cores or that uses multithreading. This allows a system to process multiple instructions concurrently. You can also add additional memory to the system. Sometimes an overutilized CPU can be caused by a system that doesn't have enough RAM installed to support the applications and services running on the processor. In this situation, the CPU must constantly swap data between the system RAM and paging file on the hard disk. This condition can get so bad that the CPU can't perform any useful work. Adding RAM to the system will quickly and dramatically improve system performance. Memory Utilization Counters 3:01-4:00 You should also monitor memory utilization. There are three counters you need to pay special attention to: The use physical memory counter identifies how much of the system's physical RAM has beenallocated to running processes. The commit charge counter identifies the amount of virtual memory that Windows is currently using.And remember, Windows uses a paging file on the hard disk as virtual memory. The Windows operating system kernel can move allocated but inactive memory addresses from RAM to the paging file on the disk. This frees up the faster physical RAM for use by active processes. If the inactive data is needed again, the kernel can move it back from the slower paging file to physical RAM where the CPU can process it again. The hard faults per second counter measures the number of hard faults that occur on the system. A hard fault occurs when the data needed by a processor is no longer in physical memory, but has been swapped out to the paging file, requiring the system to look for it on the hard disk when it is needed again.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
