version 3.6 was faster than 3.5 by 12%



Even though Chrome beat Firefox by a wide margin when it comes to speed, Firefox appears to be better than Chrome when it comes to memory footprint when multiple tabs are open. With five identical tabs open in each browser, Chrome used 194.6MB versus 100.3MB in Firefox. That is partly by design, though, because Chrome uses separate processes for each tab, which leads to a larger memory footprint when multiple tabs are open.

The upside of this for Chrome (and for Internet Explorer 8, which uses the same technique), is that when an individual tab crashes, only that tab is brought down, and the browser itself remains running. With Firefox, when one tab crashes, it generally brings down the browser.

To be clear:JavaScript is used in the DHTML facilities of the browser which can change the presentation (eg: mouseOver effects) and perform form field validations (eg: email address must contain '@' and at lease one '.') Thus, this benchmark does not address raw performance of loading and rendering pages.

In addition, there are multiple DHTML scripting implementations:

JavaScript: the W3C standard

JavaScript is a scripting language developed by Netscape Communications designed for developing client and server Internet applications. Netscape Navigator is designed to interpret JavaScript embedded into Web pages. JavaScript is independent of Sun Microsystem's Java language.

JScript

Microsoft JScript is an open implementation of Netscape's JavaScript. JScript is a high-performance scripting language designed to create active online content for the World Wide Web. JScript allows developers to link and automate a wide variety of objects in Web pages, including ActiveX controls and Java programs. Microsoft Internet Explorer is designed to interpret JScript embedded into Web pages.

Good points!

I included the part I thought was relevant:

1) Memory usage
2) Separate processes for each tab

The main thing that I see, is that if one tab crashes in Firefox normally the whole browser comes down. They are efficient at recovering the tabs, but in Chrome often only one tab will crash leaving your other tabs still up.

I do use firefox primarily, but found that interesting.

Here are two online benchmarks you can run for yourself:

This one appears to be thorough, testing many, if not all browser features: Peacekeeper

This is a CSS (Cascading Style Sheet) test: be sure to follow the directions. CSS

On the peacekeeper page I am getting

"Could not find result for key null. If you trying to benchmark another browser please make sure you have copied the url correctly and try again."

I have have switched to Chrome for the forseable future.

IE is a security black hole and Firefox was constantly causing me issues. Opera was a nice alternative to but I like the Chrome interface more.

As you say it seems faster and when it crashes it doesn't seem to bring the whole browser down unless an applet such as flash or java was to fail. Then the whole thing comes down but It will save every tab to cache before doing so, so when you start up its logged and knows what you were doing at the time.

Its pretty neat
