Microsoft: Sites using IE 10 and HTML5 load 30 percent faster

On Wednesday, Microsoft announced how Internet Explorer 10 while running in Windows 8 was made to offer better JavaScript performance for websites. Today, the Exploring IE blog offers even more information on how website performance is improved with IE 10, this time with sites  programmed with HTML5.

Microsoft says that website designers who change their code to have them be more compatible with HTML5 will see a massive increase in page loading under IE 10. The blog states. "In fact, we found that sites in IE 10 got an average of 30 (percent) better page load time when they switched to Standards Mode. The benefit is similar in IE 9 too."

Microsoft said it has worked with developers at a number of major sites to help them improve their page load times by having them rendered in Standards Mode. Often, the change was based on just one or two lines of code to force the sites to run in Standards Mode. Microsoft claims the results were pretty impressive.

For example, load times for HP.com were 39 percent faster with the changes while the photo website Shutterfly.com saw its page load times get 33 percent faster. CNN.com had 11 percent faster page load times and the Southwest.com site experienced 23 percent faster load times with the changes.

In addition to altering one or two lines of code, faster load times can be generated by site designers updating their frameworks and libraries. Microsoft also said that some websites used webkit-based prefixed code made to run on Google's Chrome and Apple's Safari browsers; Microsoft claims using other web standards that were the equivalent to webkit solved this issues.

Microsoft says that web developers can check out the company's F12 Developer Tools in both IE 10 and IE 9 to check out how their sites load in various rendering modes.

it says that IE9 sees a similar speed increase. So it isn't really IE10 that is great it is that HTML5 renders quicker.

How about this...

The way the IE9 and IE10 engine handles content by treating as much as possible like code and 'running' it rather than displaying it, can gain far more speed from HTML5 due to the structure of the standards.

This is like the difference between and interpreter reading jumbled and inconsistent code, compared to tight and well defined code.

The reason this HAS relevance to IE9 and IE10 is that they treat content like code and essentially 'run' a web page/site. All other browsers still treat content like a document that is then displayed.

This base 'model' difference is why Chrome and Firefox still cannot compete with even IE9 on very complex and rich HTML5 content.

There are still very simple graphical HTML5 tests that run faster on a WP7 with IE9 than on Chrome on a i7 x64 Windows desktop. That is a LOT of difference, and with that much 'variance' with Chrome and Firefox being so CPU and display bound being 'document display' applications, it is hard to develop good HTML5 content and expect a Netbook user that likes Chrome to have a good experience, where the Netbook users with IE9 will have a similar experience to the i7 x64 Windows desktop user.

PS The other thing of note is getting web developers to stop using Webkit crap and expecting every browser to run it even though it is not standards code. Also coding for WebKit specifics and expecting other browsers to 'downgrade' their capabilities to take time to run the Webkit code is hurting the web.

This is along the same line of thinking of why you DO NOT use Sunspider as benchmark for non-webkit browsers, as it was DESIGNED FOR and SPECIFICALLY is testing things the way WebKit deals with them, from its optimized memory usage blocks to how it handles strings.

^This.

Web Devs need to make their sites by detecting features and having specific CSS for the unfinished items in the spec that still use vendor prefixes.

Stop using vendor prefixes for what are pretty much finalized parts of spec.
I h8 WebKit devs that think the web doesn't exist without webkit.

i'm ready for ie 10! will its release coincide with w8?

Most likely. The end of this year is going to be a busy one for Microsoft.

Where is IE10 for WIn7? I haven't seen anything out of them re: that since the first platform preview on April 2011.

Next time we see it on Windows 7 it'll be when it goes final I bet. I thought they'd release a RC when the Windows 8 RP went out but that didn't happen, so it's RTM only now.

I suspect that they want to drive up news about Windows 8 rather than letting people know that they can hang around with Windows 7 while still getting IE10. They had previously announced that Windows 7 users will get IE10 though.

Windows 7 years at least should get IE10, but Vista users, I dunno. It seems that now MS has went to the model were the newest version of IE supports the 2 newest OS versions only and leaves 3rd and older out of the mix. Though I see no reason why Vista shouldn't be able to run IE10 as well unless it's got something to do with the older WDDM version in Vista compared to 7 and 8.

MIcrosoft acknowledging that no one wants to willingly use Windows Vista.

Another person making fun of Vista, so original.

I'm the biggest ms fanboy I know. I also make fun of Vista, and Server 2008.

Win7 fixed so many architectural issues with Vista that no amount of service paks would fix.

"HTML5 sites load 30% faster in IE10" would have been a better title, the current one makes out IE10 to be some kind of spec like HTML5 is.

Totally agree with you, the title is misleading, a website can't use a browser, IE 10 it's not a programming language nor anything similar, it's a browser, so again, the title should be changed as you suggested, but this is just another post from John.
