The Microsoft Edge web browser is based on Chromium and was released on January 15, 2020. It is compatible with all supported versions of Windows, and macOS. With speed, performance, best in class compatibility for websites and extensions, and built-in privacy and security features.

Microsoft Edge proactively takes steps to minimize resource usage when your device is under pressure to keep your device running smoothly. One way Microsoft Edge does this is by putting tabs to sleep when memory pressure is detected on your device. Sometimes the proactive steps that Microsoft Edge takes are not enough to completely resolve the issue. For those instances, Microsoft built a feature called the Performance detector.

The performance detector helps identify high resource usage (memory (RAM) and/or processing power (CPU)) of background tabs and when an issue is detected, provides a way for you to fix it.

In the performance hub, when resource usage is normal, the Performance detector will say Low usage next to Memory and CPU and the gauge below it will be green.

When Microsoft Edge detects that your background tabs are using too much memory (RAM) and/or processing power (CPU), a heart pulse icon with a red dot will appear in the toolbar to indicate an issue has been identified.

If you select this icon, the Performance detector will say High usage next to Memory and CPU and the gauge will be red to indicate an issue has been detected. Website tabs that are using the most memory and/or CPU will be listed under the gauge.

To help bring your background tabs memory and/or CPU usage back to green, you can use the performance detector to close or put to sleep high usage tabs.

Reference:

This tutorial will show you how to enable or disable the tab Performance detector in Microsoft Edge for your account or all users in Windows 10 and Windows 11.


Performance detector is currently only available in the Microsoft Edge Beta and Canary channels.
