It’s not that simple, because to be fair, Microsofts test was also biased. What was that all about? Well, the basic setup was the following: take 4 fully charged Surface Books, open on all 4 a different browser (that being Edge, Chrome, Firefox and Opera) with their default settings and start watching a Netflix movie. Let’s begin at the begin: Microsofts own test.

So yes, I am perhaps biased towards Edge, and that’s why I’ll try to keep my opinion out of this as much as possible. The toggle is available in the “System” section of the settings menu.Let’s get some things out of the way: first off, Edge is my main and favorable browser, simple because I also use Windows 10 Mobile and the integration is just amazing.

Performance Mode is rolling out now in version 91.0.856.0, available in the Canary channel. “Sleeping Tabs” essentially freezes a tab that’s left open in the background, saving resources when it’s not actively being used. One specific change Microsoft notes is that the “Sleeping Tabs” feature in Edge will be locked to five minutes when performance mode is turned on. Performance improvements might vary depending on your individual specifications and browser habits. Performance mode helps you optimize speed, responsiveness, memory, CPU and battery usage.

Apparently, the mode may adjust based on your browsing habits too. In practice, Microsoft says the new mode will improve speed and responsiveness overall while “optimizing” the use of battery, CPU, and RAM. Rolling out first to the Canary channel, “performance mode” in Microsoft Edge is designed to improve how the browser uses the resources available to it. The latest addition coming to Microsoft Edge is “performance mode.” After switching to Chromium, Microsoft Edge exploded in popularity and quickly became the second-most popular desktop browser, and now, it just continues to add useful features to tempt away Chrome users.
