Google Chrome is my new default browser. It is too awesome to try and convey with mere words. It is lightning quick, on EVERYTHING. Even my Yahoo Mail account which is always sluggish due to the heavy scripting. It is, the browser I have always wanted, right now. Goodbye IE, Goodbye Opera and Goodbye Firefox, you won't be missed.
The genius behind it all is that each webpage isn't just managed well or given it's own CPU thread, but instead managed by the browser like a process. And then for each page there are sub processes. So say a YouTube page will have the page as a process and then the flash object as another.
Chrome uses a relatively HUGE amount of memory to what we are used to from a browser. Right now with four windows open it is using 36MB of memory, but it is SO worth it.
Google have put together a Comic explaining their philosophy behind Chrome and some of the technical 'How We Did It' stuff. And please give it a try.
