According to the latest news, Microsoft is developing a new feature for Google Chrome that will increase the loading speed of Chrome’s internal web pages on Windows, Linux, macOS and other desktop platforms. In the new Chromium code submission, Microsoft revealed that it is developing a new code cache for scripts obtained through the chrome://protocol.
After the script is loaded and executed, V8 can be serialized into the interpreter bytecode generated by the script. Later, if Blink tells V8 to run the same script again and provide the previously serialized bytecode, then V8 can skip the initial parsing step and the script will run faster. This is important for page load time.
Chrome and other Chromium-based browsers contain some large scripts in WebUI pages, and WebUI is used in some common scenarios, such as new tab pages. Microsoft said that after using the new code cache, the time to draw the first content on the new tab page has been reduced by 11-20%.
Currently, this feature is disabled by default, and you can enable it by using the –enable-features=WebUICodeCache command.
