Microsoft Edge 100 improves Sleeping Tabs ability to save more resources

Microsoft Edge 100 was released a few days ago and is essentially a security update. The Redmond-based company highlighted that the latest version improves browser performance with a more optimized version of Sleeping Tabs.

The feature debuted in September 2020 when Edge Canary 87 was released. It was rolled out to all users in Edge 89 in March 2021. When you surf the web and hoard a bunch of tabs, the browser starts consuming more resources, which leads to a drop in system performance. Sleeping Tabs monitors tabs that you haven’t used for a while i.e. inactive tabs and puts them to sleep mode automatically. This is also known as tab unloading, tab discarding or tab snoozing. Edge isn’t the only browser that supports it natively, it’s also a feature you can find in Google Chrome, Mozilla Firefox, Opera, and Vivaldi. Waterfox G4.1.0, released yesterday, added tab unloading and allows you to move tabs manually. Brave Browser is the only one that doesn’t natively support tab snoozing, but that can easily be fixed by using an extension like Auto Tab Discard.

I think we can all agree that sleeping tabs is a handy feature and Microsoft Edge 100 continues to improve on it. The company’s announcement states that Edge will hibernate 8% more tabs to save more resources. How does this work? Pages that share a browsing instance with another page are hibernated. This allows Sleeping Tabs to save up to 85% memory and an average of 99% CPU usage. If you change the efficiency mode to Always in the Performance pop-up, tabs will snooze faster.

That’s pretty impressive, and if you’re interested in crunching the numbers, you’ll probably like this. Edge 100 added a new performance monitor to show users how Sleeping Tabs helps save system resources. To access it, click the three-dot menu and choose Performance. This will open a pop-up window showing the number of sleeping tabs and a graphical gauge showing you the percentage of memory savings with sleeping tabs and the remaining usage. You can pin the performance monitor to stay on top to keep an eye on resource usage. It’s a decent way to monitor the system, although Windows’ Task Manager still beats it because you can get a per-tab breakdown of resource usage.

There’s no option to manually hibernate tabs, although users have requested the feature on Microsoft’s Feedback Hub. You can whitelist websites in the “Optimize performance” section of the edge://settings/system page. This prevents Edge from shedding tabs from the websites. This can be useful for websites that you use for email, instant messaging, sports websites that refresh automatically to update results, etc. You can set tabs to be shelved after a certain amount of time. eg 5 minutes. toggle the

Don’t like the feature? You can turn off sleeping tabs in Edge from the Settings page.

Edge 100 also brought some new features such as: Examples include the ability to preview PDF files using File Explorer and Microsoft Outlook powered by Edge’s Web View, and support for viewing PDFs that have been digitally signed.
