Google Chrome 57 has reduced memory and CPU usage

Today it is impossible to imagine a web browsing without tabs. Any modern web browser today has this feature that allows us to load several web pages at the same time within the same window, switching from one to another with a single click. However, this feature has also brought some problems, and is that these tabs, although not open on the screen, can consume a lot of resources on the computer. With Google Chrome 57, this is no longer a problem.

Google Chrome has not been synonymous with lightweight browser and low resource consumption

Historically, Google Chrome has not been synonymous with lightweight browser and low resource consumption. The Google browser is much more than a simple browser because, among other things, it loads into memory the entire core of Chrome OS that allows us to run applications within the browser itself operating almost as a separate operating system. Users who often have several tabs open at the same time will also have seen how the CPU usage would soar to the point that even the rest of the computer could start malfunctioning.

Google Chrome 57 is now available. These are the new features of the new version of the Google browser.

With the arrival of Google Chrome 57 a week ago, the company has wanted to do away with this problem once and for all, and for this, has implemented a drastic measure in the browser that limits to only 1% CPU usage to the tabs that are in the background. In addition, it stops the JavaScript code of these tabs in the background so that they are really left hanging in the browser.

Some websites such as Facebook, Twitter, Gmail, Slack, YouTube or Evernote, among others, use these “counters” JavaScript to stay active and be always up to date. However, as Google claims, many developers abuse these accountants, so they have been forced to make this decision.

Pages that play audio or use real-time controlled connections such as through WebSockets or WebRTC have not been affected at this time.

Thanks to this suspension, the consumption of resources and the expense of battery have been reduced considerably. If we have not downloaded it, the new Google Chrome 57 is available for free from the following link. Download Google Chrome 57

If we want a much more radical limitation, Google allows us to enable the experimental functions by adding the following parameter to the shortcut from which we launch the browser:


Google will continue to limit the activity of websites in the background of Google Chrome over the next few years

This measure is only the first of a project that will last for several years during which Google will increasingly limit the use of resources of the tabs and processes in the background in your browser.

Throughout 2017, the company will definitely block all processes in the background (not only the JavaScript counters) on mobile devices and will also begin to limit web applications checking that they are not abusing this measure. By the end of this year, the browser will also begin to limit all content that is not displayed on the screen.

Throughout 2018, the browser will be much more radical with the processes loaded in the background of the tabs and, in addition, it will begin to block by default all the activity of the tabs that remain active for more than N minutes, except that an explicit function declares otherwise.

Finally, from 2020, all pages loaded in the background will be completely suspended.

What do you think of this new feature? Do you think it was necessary to limit the use of these websites in the background?
