With Google Chrome released, one of its most awesome features is the excellent JavaScript performance. It is a complete new re-write of the JavaScript VM and uses what is called the V8 Engine by the Google developers who worked on the new JavaScript engine. Here is a JavaScript Performance Analysis for developers to look at comparing different browsers.
Google uses a lot of AJAX and the new V8 engine is the king in JavaScript performance done using Dromaeo :
| Browser | Time (lower the better) |
| Chrome 0.2.149.27 | 488.80ms |
| Firefox 3.0.1 | 1775.00ms |
| Opera 9.52 | 1767.60ms |
| Safari 3.1.2 | 2075.00ms |
The memory usage of Chrome is also pretty good and the built-in task manager for looking at the memory/CPU usage of tabs is interesting and useful. It can also help in analyzing which tab is creating some kind of menace or using more memory. You can close that tab and get some free memory. This is just an initial preview, but the JavaScript performance is top-notch!!

Hoots to V8!
I find google chrome a very useful and fast browser as comparing to internet explorer and firefox. One thing which I have noticed on my computer is that as I use internet explorer and firefox to explore web pages my windows slow down as I open more pages but using google chrome it doesn’t happened! my windows performance increased using google's new browser CHROME I LOVE IT!
Great write up.
