Introduction to diskperf.exe and its importance in Windows 11

Diskperf.exe is a command-line tool available in Windows 11 that allows users to enable or disable disk performance counters. These counters provide valuable information about the performance of your storage devices, including disk read and write speeds, average disk queue length, and disk utilization.

Understanding and monitoring disk performance is crucial for maintaining the overall health and efficiency of your system. By using diskperf.exe, you can enable these performance counters and collect data for analysis, troubleshooting, and optimization purposes.

Examples:

1. Enabling disk performance counters: To enable disk performance counters using diskperf.exe, follow these steps:

   1. Open the Command Prompt as an administrator.
   2. Type the following command and press Enter:

      diskperf -y

   3. This command enables disk performance counters on all physical and logical disks in your system.

2. Disabling disk performance counters: If you no longer need to collect disk performance data, you can disable the counters using diskperf.exe. Here's how:

   1. Open the Command Prompt as an administrator.
   2. Type the following command and press Enter:

      diskperf -n

   3. This command disables disk performance counters on all disks.

3. Checking the status of disk performance counters: To check whether disk performance counters are currently enabled or disabled, use the following command:

   diskperf -s

   This command displays the status of disk performance counters for each disk.
