At this week's Build 2021 developer conference, Microsoft is introducing two performance-enhancing features in Microsoft Edge version 91: tabs for hibernation and a boot boost. The company also pointed out some milestones for the browser.

With the Start Boost feature, Edge can now respond faster by running a number of Edge core processes in the background without adding additional resources when existing windows are open. You can use this function to quickly return to the action after switching on the PC again.

With sleeping tabs, Microsoft Edge works better when multiple tabs are used at the same time. Under the hood, Edge frees system resources from unused tabs. The feature was previously available in version 90 of Edge, but Microsoft says it's now even more streamlined. Sleeping Tabs can now save up to 82% memory based on Microsoft's internal data.

While these are the most important features for consumers, Microsoft has released some updates to the web browser's developer page. Since the build last year, Microsoft claims to have made more than 5,300 commits available for the open source Chromium project. It also worked with developers to bring more progressive web apps to the Microsoft Store in three easy steps. Finally, Microsoft also has plans to help those who may be affected by the retirement of Internet Explorer 11.

“Since the last build, the Microsoft Edge platform has continued to provide developers with the latest tools ready for today's evolving web landscape. We hope you enjoy Microsoft Build this year and that you are excited about all of the new developer innovations, ”said Microsoft.

Edge 91 launches this week. You can download the update today by clicking the three right-facing dots next to your profile icon, selecting Settings, going to About Microsoft Edge, and then restarting your browser.

If you'd like to try these features out before a general release, the easy way to do that is by joining the Microsoft Edge Insider Program. Just visit the Microsoft website and choose a channel. The Dev Channel is usually the most stable while the Canary gets features quickly. The release plans are in line with what Google is doing with its own Chrome web browser.
