Question

Take a random web page with JavaScript on the web. Are there any numbers on what the share of JavaScript is on the global load/execution time?
I mean, if that share would be close to 0%, there would be no benefit in optimizing the JavaScript interpreter, nut as we all know, you can make some money with a fast interpreter 🙂
I guess companies like Google and Mozilla have such numbers, but I couldn’t find them.

Can someone point me to some numbers?

thanks in advance

Performance: Profiling how different web sites use browser subsystems

Bringing It All Together

To build a fast real world browser you have to understand how different browser subsystems impact performance in real world scenarios, and you have to focus on the subsystems that matter.

For AJAX sites, that means focusing on Rendering (31%), JavaScript (21%), Formatting (14%) and Layout (12%). For news sites, that means focusing on JavaScript (29%), Marshalling (18%) and Rendering (17%).
