In June, Microsoft bragged that its new, Chromium-based Microsoft Edge could see a 27-percent drop in memory use in conjunction with the Windows 10 May 2020 Update. Google said it would follow Edgeâ€™s lead. Now both browsers will see that advantage eliminated after a performance bug was found.
While the new Chromium-based Edge browser Microsoft launched earlier this year had some issues with synchronizing data, it was a lean, mean browserâ€”and still is. But it was supposed to become even leaner with the May 2020 Update (2004)â€™s release, because of memory allocation improvements in the segment heap. Because Microsoft now contributes to Chromiumâ€”the open-sourced underpinnings of both Google Chrome and Microsoft Edgeâ€”the segment heap improvements could be applied to Chrome as well, reducing the memory usage of that browser.
