Last month, we reported that
Google has been internally testing a new feature that could
significantly reduce memory usage on Windows 10. With Chrome
89, which is now available for download, the search giant has
finally enabled ‘PartitionAlloc-everywhere’ support for its
Google has confirmed that Chrome 89 features better tab
throttling, discard and better resource management with
This feature is supposed to improve the way in which Google
Chrome performs on Windows 10. According to Chromium commits,
‘PartitionAlloc-everywhere’ support allows the browser to
reduce RAM usage, load webpages faster and offer improved
processor power management.
PartitionAlloc-everywhere feature comes with an advanced memory
allocator to reduce memory usage of Chrome by up to 22% in the
browser process. Likewise, Google says the update has reduced
memory usage by 8% in the browser’s renderer, and 3% in the
Google Chrome has also become 9% more responsive, thanks to the
new tabs discarding improvements.
Chrome 89 represents a minor drop in memory usage of foreground
tabs as well. To reduce the memory usage of foreground tabs,
Google Chrome will now discard the foreground tab automatically
and reclaim up to 100MiB per tab, which could be more than 20%
on some popular sites.
In addition to performance improvements,
Chrome 89 for Windows 10 also comes with early support for the
modern share UI, which could soon allow you to easily share
webpages via other installed apps, such as Outlook and OneNote.
You can even use the modern share feature to send webpages to
nearby devices over Wi-Fi and Bluetooth.
These changes are rolling out with Chrome 89 for Windows and
Google is already testing additional improvements.
For example, Google plans to purge thread cache periodically in
child processes of Chrome. This happens on a per-process basis,
which should improve the overall performance for GPU, rendering
