What is the Performance Monitor utility, and how can it be used to troubleshoot system performance?
What will be an ideal response?
Performance Monitor is a powerful monitoring tool that you can open from Server Manager, the Windows Administrative Tools folder through the Start button, or as an MMC snap-in. Performance Monitor can be used to monitor components such as hard disks, memory, the processor, a network interface, a started process, and the paging file. For example, you might monitor memory and the paging file to determine if you have fully tuned the paging file for satisfactory performance and to determine if you have adequate RAM for the server load.
