Google switches off Chrome memory savings in Windows

Windows should be a memory hog like Android

Google has decided to disable a feature in Windows 10 version 2004 that allowed Chrome and Microsoft Edge browsers to use a lot less RAM.

Windows 10 gave Win32 apps including Chrome access to a ‘segment heap’ API to allow apps to reduce memory usage.

However, Chromium engineers have decided for now to turn off the feature by default in Chrome 85 after discovering it caused a hit on the CPU.

The CPU issue was discovered by an Intel engineer who found that when Chrome used segment heap, it led to significant performance regression in benchmarks on a PC with an Intel Core i9-9900K processor.

Microsoft has defended the trade-off between memory and CPU but conceded it could be implemented better to reduce the impact on CPU performance.
