<p>While browsing with Chrome, I noticed that it responds extremely fast (in comparison with IE and Firefox on my laptop) in terms of rendering pages, including JavaScript heavy sites like gmail.</p>

<p>This is what googlebook on Chrome has to say </p>

<ol>
<li>tabs are hosted in process rather than thread.</li>
<li>compile javascript using V8 engine as opposed to interpreting.</li>
<li>Introduce new virtual machine to support javascript heavy apps</li>
<li>introduce "hidden class transitions" and apply dynamic optimization to speed up things.</li>
<li>Replace inefficient "Conservative garbage colllection" scheme with more precise garbage  collection scheme.</li>
<li>Introduce their own task scheduler and memory manager to manage the browser environment.</li>
</ol>

<p>All this sounds so familiar, and Microsoft has been doing such things for long time.. Windows os, C++, C# etc compilers, CLR, and so on. </p>

<p>So why isn't Microsoft or any other browser vendor taking Chrome's approach? Is there a flaw in Chrome's approach? If not, is the rest of browser vendor community caught unaware  with Google's approach?</p>
