But that is not the case in the newer method. Chrome can now work in sync and defer scripts on a separate thread as soon as the download begins. This simply means the entire script need not be downloaded before the browser can start to parse this and also, there wasn’t much work for CPU during the downloading process. This helps in saving sometime in the progress by taking benefit of the computer’s CPU.
According to Google, this feature enables the pages to load up 10 times faster. The script screaming process is specially effective when large scripts are being used on the page and also if the user is on slow network connection.
The process helps in reducing 40% of compilation time thereby not only helping the pages load faster but can also cut down the energy consumption of the mobile phone’s battery when used on smartphones. This new feature can be found in the latest update of Chrome 41.
