The most popular browser in the world will receive one more update. And, according to Google, it will be “extremely fast”. But only on pages you’ve visited. The feature to be implemented in Chrome is nothing new. Mozilla and Safari already use this method to speed up navigation. Named bfcache (backward / forward cache), the loaded sites are stored as soon as the user accesses a new address; if it returns to the page, it is read directly from memory.
Although it seems superfluous, bfcache will meet an obvious demand. About 19% of in-app visits and 10% in browser desktop are pages that have already been visited, according to Google. Therefore, the change should result in significantly faster navigation.
In addition, for the mobile user, the feature can mean an improvement in overall application performance. Using multiple tabs will consume less RAM, and pages placed in the background will reload faster.
Not everything is flowers
Google is also aware of the excessive consumption of memory that the new feature can cause; however, it is still working out ways to understand which pages should be saved.
It is expected that bfcache will be tested this year and released in 2020.
