谷歌Chrome是全球第一大浏览器，好用、方便是公认的，然而吃内存和CPU也是一大问题，尤其是标签开多了的情况，为此谷歌也在测试版Chrome中引入了新的杀后台技术，可以快速降低资源占用。
谷歌现在Chrome Canary v105中引入了新的实验功能，该版本的Chrome比稳定版、开发版更新更勤快，通常是用来测试新技术的，这次的新功能就是可以快速冻结标签页，降低CPU和内存占用以延长续航时间。
这个新功能简单来说就是标签杀后台，而且比之前以后的标签管理技术更激进，之前是标签切换到后台超过5分钟后才会被冻结，现在的杀后台阈值是10秒钟，也就是说你离开这个标签没多久就会导致这个标签被冻结。
这样做的好处显而易见，10秒钟可以保证快速释放标签占用的CPU及内存资源，然而代价也是有的，如此激进杀后台，你再切回这个标签就要重新加载。
总体来看，这个功能适合内存较小、对续航要求较高的场景，如果不担心续航，内存、CPU也不差的话，比如台式机平台，建议就不要开了。
开启这个功能除了需要Chrome Canary v105浏览器之外，还要在地址栏输入chrome://flags/#quick-intensive-throttling-after-loading找到设置，将其改为Enabled后重启浏览器即可。
谷歌Chrome浏览器杀后台功能升级：降低CPU、内存占用
Google Chrome is the world's largest browser. It is recognized that it is easy to use and convenient. However, it is also a big problem to eat memory and CPU, especially when there are too many tabs. For this reason, Google also introduced a new browser in the beta version of Chrome. Killing background technology can quickly reduce resource usage.
Google has now introduced a new experimental feature in Chrome Canary v105. This version of Chrome is updated more diligently than the stable version and the development version. It is usually used to test new technologies. This new feature can quickly freeze tabs and reduce CPU. and memory usage to extend battery life.
This new function is simply a tag to kill the background, and it is more radical than the previous tag management technology. Previously, the tag will be frozen after switching to the background for more than 5 minutes. Now the threshold for killing the background is 10 seconds, which means that It doesn't take long for you to leave the tab that will cause the tab to freeze.
The advantages of doing this are obvious. 10 seconds can guarantee the quick release of the CPU and memory resources occupied by the tag, but there is also a price. If you kill the background so aggressively, you will need to reload the tag if you switch back to the tag.
In general, this function is suitable for scenarios with small memory and high battery life requirements. If you are not worried about battery life, and if the memory and CPU are not bad, such as desktop platforms, it is recommended not to open it.
In addition to the Chrome Canary v105 browser, you need to enter chrome://flags/#quick-intensive-throttling-after-loading in the address bar to find the setting, change it to Enabled, and then restart the browser.
