How to measure a computer's performance
Using Windows utilities
Windows Task Manager Performance Tab
Microsoft Windows comes with some basic monitor tools that help you monitor and measure a computer's performance. For example, open the Windows Task Manager (press Ctrl+Alt+Del) and click on the Performance tab. As can be seen in the example below of the Windows 7 Task Manager tab the screen gives you an overview of the CPU Usage, memory, and other good system information.
Windows Resource Monitor
Windows Vista, Windows 7, Windows 8, and Windows 10 users can open the Windows Resource Monitor from the Performance tab by clicking the Resource Monitor button, or the Open Resource Monitor link.
The Windows Resource Monitor is a great tool that was first introduced in Windows 7 and gives much greater detail of the overall system performance of a computer. The Resource Monitor also gives you disk and network related information.
Using third-party utilities
The Windows utilities listed above are great for giving an overview of the current performance of Windows and the running programs. However, they are not designed to give you an overall ranking or comparison. If you need more details about the system performance, we suggest a benchmarking program. These programs are designed to test the overall system performance and give you an overall rank that can be used for testing purposes or to compete against others.
