"Microsoft explains that the latest update for Windows 10 introduces a new “SegmentHeap” value for developers, which is a modern heap implementation that “will generally reduce your overall memory usage” on Windows 10 version 2004 or newer. The company has confirmed that it has already started using the new value in its Chromium-based Edge browser, with early tests showing a memory reduction of up to 27% on the Windows 10 May 2020 update.

Google Chrome could also benefit from the new value, and according to a recently added commit on the Chromium Gerrit, a change may be coming soon. In the commit, a Chrome developer notes that adding the “SegmentHeap” entry to the chrome.exe manifest will tell Windows 10 2004 or newer to opt chrome.exe into using the segment heap instead of the legacy heap. The developer further notes that “Experiments with per-machine opting-in to the segment heap for chrome.exe suggests that this could save hundreds of MB in the browser and Network Service utility processes, among others, on some machines.”

"Segment Heap has been available to UWP applications only in previous versions of Windows 10"

Any idea if there are plans for Firefox to use this feature?

I doubt too many devs are jumping on the Win 2004 bandwagon at the moment the upgrade has turned into an epic screw up even by Microsoft standards ... llout.html
