The speed that it takes for a browser to reload a page is important because if you think of it, we tend to reload quite a few times a day when we want to see what’s new on the news feed or our network connection isn’t particularly the best.
So what happens when you reload a page? The browser checks with the web server if there are any cached resources left. This process is called validation and it usually results in hundreds of network requests per page issued to dozens of domains. Now, this will probably not be a problem on a desktop PC but on a mobile device where connections aren’t that good it can lead to major performance issues and high latency.
The Chrome update should change the mechanism of reloading a page. Instead of going trough the whole validation process will only validate the main resource and continue with a regular page load. This behavior should maximize the use of cached resources and result in lower latency, power consumption, and data usage. The developing team claims that reloading times should become 28% shorter and validation request will be 60% less. Here is a video demonstration:
If you are interested you can check out some Chromebooks as they will probably work best with every Google or Chrome update.
