Turn off a checkbox to hide it from the graph. The memory usage is broken down by JS heap (same as HEAP graph in the Overview pane), documents, DOM nodes, listeners, and GPU memory. Below the Overview pane is the Counter pane. The HEAP graph in the Overview pane (below NET) represents the JS heap. Select Shift+ Esc or navigate to the Microsoft Edge main menu and choose More tools > Browser Task Manager to open the Microsoft Edge Browser Task Manager.įirst, an explanation of the user interface. The Microsoft Edge Browser Task Manager is a realtime monitor that tells you how much memory a page is currently using. Use the Microsoft Edge Browser Task Manager as a starting point to your memory issue investigation. Monitor memory use in realtime with the Microsoft Edge Browser Task Manager If the experience is consistently bad, the page may be exceeding the memory capabilities of those devices. Find out what devices are popular with your users, and then test out your page on those devices. The key here is to use the RAIL model and focus on your users. Runs smoothly on a high-end smartphone may crash on a low-end smartphone. There are no hard numbers here, because different devices and browsers have different capabilities. What qualifies as "using too much memory"? But memory bloat is a bit harder to pin down. If a site is progressively using more and more memory, then you have a leak. So if the browser is garbage collecting a lot, script runtime is going to get paused a lot.Ī memory leak is easy to define. During collections, all script running is paused. Garbage collection is when the browser reclaims memory. This is possibly a symptom of frequent garbage collections.
Memory issues are important because they are often perceivable by users. In the spirit of the RAIL performance model, the focus of your performance efforts should be your users. Find out when new memory is being allocated in your JavaScript heap (JS heap) with Allocation instrumentation on timeline.Identify detached DOM trees (a common cause of memory leaks) with Heap snapshot.Visualize memory usage over time with the Memory panel.Find out how much memory your page is currently using with the Microsoft Edge Browser Task Manager.
