Google Chrome’s RAM usage could be reduced on Windows – 9to5Google

You’ve seen the memes. Google Chrome absolutely eats RAM on most computers, especially on Windows. Now, though, a change to Windows 10 that is live in the latest update opens the door for Google Chrome to reduce its usage going forward.

The Windows 10 May update, as the folks over at Windows Latest point out, introduces segment heap memory improvements. What is that? The short story is that it’s a method to reduce overall memory usage of Win32 apps, such as Google Chrome, on the latest versions of Windows. This change is available to developers in Windows version 2004 or newer.

“SegmentHeap” is already being used by Microsoft’s Chromium-based Edge browser as detailed in a recent blog post. When implemented, it shows a memory reduction of up to 27% in early tests.

Early internal testing results of devices on the May 2020 Update are showing a memory usage reduction of up to 27% when browsing with Microsoft Edge. Individual device performance will vary based upon configuration and usage, but the lower memory usage is expected to create a better experience.

In a Chromium commit, engineers discuss using “SegmentHeap” on Google Chrome. The engineer mentions that implementing the change could save “hundreds of MB in the browser and Network Service utility processes” on some machines, with “many-core” machines benefitting the greatest from the change.

There may be one considerable roadblock, though. Implementing “SegmentHeap” in Google Chrome for Windows would reduce RAM usage, but it would require Google to build with the Windows 10.0.19041.0 (20-04) SDK. Apparently, this is difficult because that version is “currently blocked on some mysterious build failures.” Hopefully, Google can work things out.

Be warned, though, the version 2004 update for Windows is still messing with Google Chrome for many users. If you can hold off for the time being, do so.
