Google Chrome will be able to instantly open tabs and not eat RAM

Google Chrome is rightfully one of the most popular, if not the most popular, browser in the world. It has many advantages in terms of convenience, but it also has disadvantages, which are expressed in the exactingness of the system. Everyone knows that Google Chrome will gobble up all the RAM that is and will not choke. For example, when I had an old MacBook Air with two gigs of RAM, it seemed to me that it was about to end its life, it was so hard for him to work with this browser. Even on the current MacBook Pro with 16 GB of RAM, it’s still sometimes easier to choose a different browser. Google understands this and is preparing an update that may not improve the situation, but without unnecessary load on the computer, it will make the browser faster.

How Google Chrome Works

Now Google Chrome works so that when you close a tab, it is instantly unloaded. This is done in order to reduce the load on the system and its RAM. When you realize that you need to open it, you do it and the page essentially reloads. This wastes time, traffic and, again, system resources. Sometimes this can be very significant, especially if you are using a browser somewhere on the road and have an unstable network connection.

As the folks at Chrome Story pointed out a while back , Google Chrome is preparing an experimental update that will address this issue. As a result, opening a closed tab should be almost instantaneous. Well, or at least very fast – much faster than it is happening now.

How Google will save tabs

Instead of clearing the data immediately, Chrome will freeze all information about the page and all its data. For a short time, it will be stored in a special cache. Thanks to this, if you decide to reopen a closed tab within a short period of time, it will open very quickly precisely because it will be saved and it will not have to be reloaded, knowing only the URL .

The development team notes that the acceleration will indeed be significant. If it seems to you that you do not accidentally close tabs and open them again so often, then I hasten to please you that the above benefit of updating is not the only one.

The “reopen tab” feature in a public design document is referred to as the “closed tab cache”. According to the doc, the closed tab cache is based on another experimental, work-in-progress rework of the “BackForwardCache” feature, which saves some of the pages you’ve recently viewed so that Chrome’s back and forward buttons work almost instantly. Now this is a much more significant innovation. At the same time, apparently, the cache will not be stored for long enough to overload the system. After a few seconds or minutes, it will be cleared and you will not notice any extra load on your device.

Which Google Chrome tabs will Quick Open work for?

The developers note that the “reopen tab” feature will work for most recently closed tabs. They are currently actively working on the “BackForwardCache” enhancement for Chrome. This cache will make forward and backward navigation instantaneous. Developers want to reuse the work done there so they can quickly restore recently closed tabs.

The main use case is random clicks, which sometimes happen to everyone. In this case, the return back will not make the user wait and the recovery immediately after the close will be instant. So the developers hope to get a big win in terms of user experience. Having the ability to instantly restore tabs with all their contents, the user will get much more pleasure from working with the browser from Google.

When will the tab cache feature appear in Google Chrome

Unfortunately, it is not yet possible to say that such an update will appear very soon, but it will be. I see no reason to abandon this promising development. Now this is a matter of technology and, having an idea, you just need to implement it, which is what the developers are doing. Most likely, it will be necessary to wait for the appearance of such a function for several months, but it’s worth it. Especially I would like to have a properly working ”BackForwardCache” function .

Someone will say that waiting a couple of seconds is not scary anyway, but imagine a smartphone on which, for example, you are trying to open the settings, and each item opens for 2-3 seconds, and not instantly. Why is it necessary, if it is possible without it? The Internet is already working, as if it were downloaded to our computer, compared to what it was about ten years ago. If there is an opportunity to speed up work  with it, it should be done.

Interestingly, the paper also notes that Chrome for Android already has a feature to cache recently closed tabs, providing a convenient mobile browser undo option . These new planned improvements should make the tab opening experience more consistent between Chrome for Android and desktop versions of Chrome.

If you have something to add to the work of Google Chrome, write about it in the comments. Our site is too large to remain unnoticed by serious market players, including Google itself. Perhaps you will throw in an idea that the company’s specialists want to implement in new versions of the software.
