Internet Explorer Project Spartan Shows Large Performance Gainsby Brett Howse on January 25, 2015 12:35 AM EST

With the release of build 9926 of Windows 10, I have had some time to get to know the new build. One of the things discussed at the Windows 10 event in Redmond was an update to the browser, codenamed Project Spartan, which is a new fork of Microsoft’s browser. There will be a lot of features coming to Spartan, such as the ability to annotate web pages with digital ink or keyboard text input, a new reading experience, and Cortana integration. It will be available on all Windows 10 devices – PCs, tablets, phones, and even Xbox. Internet Explorer has never been on the fast update cycle that other browsers are on – namely Google’s Chome browser and Mozilla’s Firefox.
As a brief history, there are of course several major browsers and many smaller ones. WebKit has become one of the dominant rendering (also called layout) engines, and powers Apple’s Safari browser on both OS X and iOS. Chrome used to be based on WebKit, but in 2013, Google forked WebCore from the WebKit project and created Blink, which is also now used by the Opera browser. Firefox has their own rendering engine, called Gecko, and Internet Explorer has used a closed source rendering engine called Trident since version 4.0.
Spartan will not be Internet Explorer. This will be a completely new browser, with a new name. Spartan will however be able to load the IE 11 engine if and when needed to maintain compatibility with older sites. For enterprises which still rely on older technologies such as ActiveX controls and Browser Helper Objects, Internet Explorer will still be available in Windows 10 for those use cases, however it will have the same dual rendering engine as Spartan, allowing modern sites to be rendered with the new rendering engine, and older sites to be rendered with IE 11.
For the Windows 10 build 9926 which was released on January 23rd, Spartan is not yet available, and will show up at a later date. However Internet Explorer does have the new Edge document mode. A small number of testers will have this mode enabled by default, and anyone who wants to test against it can manually enable it by going to about:flags in the address bar. Switch Enable Experimental Web Platform Features to Enabled, and you will be using the latest rendering engine. This is still pre-release software, so enable at your own risk of course. Also in the experimental features is the ability to set a custom user agent string, and Microsoft has continued the successful strategy that they brought forward in Windows Phone 8.1 Update 1 of having a user agent string say that it is not Internet Explorer to avoid old IE-only content.
WebM support Let’s take a look at the numbers.
|Browser Performance - Core i7-860|
|Benchmark||IE Old||IE Experimental||Chrome 40||Firefox 35||Percentage Change|
|Sunspider (lower is better)||149.7ms||144.6ms||260.9ms||220.1ms||3.4%|
|Octane 2.0 (higher is better)||9861||17928||17474||16508||81.8%|
|Kraken 1.1 (lower is better)||3781.2ms||2077.5ms||1992.8ms||1760.4ms||45.1%|
|WebXPRT (higher is better)||913||1083||1251||1345||18.6%|
|Oort Online (higher is better)||1990||2170||5370||3900||9%|
|HTML5Test (higher is better)||339||344||511||449||1.5%|
IE was well optimized for Sunspider already, so there is not much of a change there. Google Octane 2.0 however has always been terrible in IE, and now it comes in roughly the same as Chrome, for a massive 81.8% increase over the old rendering engine. Kraken continues this with a 45% jump in performance. It is a big change, and a welcome one too.
Spartan should have good performance when it is eventually previewed, and hopefully the standards support will increase as well. Since it will be updated through the Windows Store, the old way of updating Internet Explorer with new Operating System releases should also disappear, allowing Microsoft to ramp up the updates to the new browser. It has taken a long time, but it seems that Redmond is finally focusing on performance and standards for a new web.

Hulk - Monday, January 26, 2015 - linkI switched to Chrome many, many years ago. And from the results of this table it looks like that's where I'll stay.
Michael Bay - Tuesday, January 27, 2015 - linkEnjoy your bloat.
Da W - Monday, January 26, 2015 - linkYay. Another fast browser. Seriously who need performance to Watch porn?
Tunnah - Monday, January 26, 2015 - linkDamn 4chan has forever ruined the phrase "large gains"
twotwotwo - Monday, January 26, 2015 - linkHuh, Octane and Kraken gains look substantial.
I think Google and Apple have (for lack of a better term) last-level compilers that do extra work optimizing heavily run code. Wonder if IE has one now, or if those results are really about DOM access speed not JS itself.
(see https://www.webkit.org/blog/3362/introducing-the-w... for WebKit's new JIT, for instance.)
sevenacids - Tuesday, January 27, 2015 - link"Internet Explorer has never been on the fast update cycle that other browsers are on – namely Google’s Chome browser and Mozilla’s Firefox."
That's a common misconception. Internet Explorer actually is updated quite frequently via Windows Update; it just doesn't reflect these incremental, comulative updates by inflationary abusing its major version counter like the other ones. As of January 2015, the current version of IE11 is 11.0.15, which means it has already received 15 incremental update since Windows 8.1 has been released.
mavere - Tuesday, January 27, 2015 - link"WebM" support is a ambiguous here. Does it also mean native VP8, VP9, and/or Opus support, or does it only signify a simple parser for the _container_ with no guaranteed extra codec support?
A new native video decoder in IE is HUGE news, so it'd be great if you could verify!
Laststop311 - Tuesday, January 27, 2015 - linkfrom what I see, yea it's an improvement but it still is losing to firefox and chrome overall. I currently use chrome and it's worked the fastest and most stable than any other browser i've used in my 22 years of using the net. I've tried all the major browsers and in my opinion chrome is the snappiest. For MS to get me to leave chrome they can't just come close to or just slightly edge out chrome they have to give me a noticeable improvement in speed and stability and they are def not there yet.
andrewaggb - Tuesday, January 27, 2015 - linkI agree overall chrome still looks faster overall.
But I'd have to look at the text rendering and smoothness of scrolling before I can really decide. In the past IE and chrome have been significantly different in this regard.
