Opera 9.5 Desktop

We've made the fastest browser in the world even faster with superior support for Web standards. Opera 9.5 is quicker to start, faster at loading Web pages and better at running your favorite Web applications.

* More than 2x faster than Opera 9.2 in rendering JavaScript and HTML
* Faster handling of third party plug-ins
* Much faster start up time
* Superior support for Web standards

I can't measure the claims above, however it sets a speed benchmark for the soon to be released Firefox 3.
