If the processor utilization is consistently high (over 90%), then the CPU is likely the bottleneck. o Check the running processes to see the CPU use of each process. If possible, delay or pause non-critical processes or run them during off hours. o A process that has hung could show 100% CPU use. If the process does not complete after a period of time and does not respond, end the process to return CPU use to normal. o A computer with a virus might show an unknown process consuming most of the processor

time. Use the Internet to identify the function of unknown processes. o Configure the processor affinity to specify that a specific process use a certain processor in a multi-processor system. o Upgrade to a faster CPU or add more cores to the system. % Disk Time (highest active time) The % Disk Time statistic identifies the percentage of time that the disk subsystem is busy reading from and writing to disk. If this value is consistently over 90%, check the following other statistics to identify the source of the high disk activity: Average Disk Queue Length Memory statistics Average Disk Queue Length The disk queue holds read and write requests that are waiting to be processed by the disk controller. The average disk queue length tells you the number of read and write requests that are typically waiting to be processed. A high number indicates that the system has requested data from the hard disk, or has tried to save data to the hard disk, but that request could not be fulfilled immediately (i.e. it has to wait). This number should be below 2 times the number of disk spindles. Most physical hard disks have a single spindle (although some newer drives have 2 or 3). RAID arrays will have at least one spindle per physical disk. If this statistic shows consistently waiting read/write requests, you might need to upgrade your disks. Choose a faster disk (higher RPM and faster access time). Use a RAID-0 configuration to improve disk access. Available, used, and free physical memory You can use Task Manager to quickly identify the use of physical memory in your system. The total installed memory value reflects the amount of memory available to the operating system. On a 32-bit system, this value will be less than 4 GB, even if you have 4 GB of memory installed. This value could also be slightly less than the amount of installed physical RAM if the video adapter shares the system memory. The amount of memory used for this purpose is displayed under hardware reserved. The cached value identifies memory that is being used for a disk cache to improve read/write operations from the hard disk. The available value identifies how much memory is unassigned. If the amount of memory in use is close to the amount of RAM installed, you might need to add RAM or quit some running programs to free up memory.

    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.
