Earlier today we announced the availability of Internet Explorer 9 Platform Preview 7. The latest platform preview incorporates end-to-end performance improvements including enhancements to Chakra, Microsoft’s JavaScript engine. Improving the performance of web applications is huge focus for web developers as consumers come to raise their expectations regarding the speed, responsiveness and richness of their experiences on the web.
In conjunction with the release of Platform Preview 7, we wanted to give the community the opportunity to ask questions of some of our IE and Chakra engineers. So we’re going to host a 2-hour Q&A chat on Twitter tomorrow morning beginning at 9am PST.
WHAT: Q&A with the Chakra team. We will be fielding your questions about JavaScript, ES5, Chakra and IE9 performance. We ask that you keep the conversation on-topic.
WHERE: On Twitter.com
WHEN: Thursday, November 18th 9-11am PST
WHO: Members of the Chakra and IE9 teams
Amanda Silver ^AS
K7 Shanmugam ^K7
Ram Cherala ^RC
Rey Bango ^RB
Travis Leithead ^TL
How to Participate: There are several simple ways to participate in the Twitter chat:
That’s it!
We look forward to talking shop on Twitter this Thursday. Come back to the Exploring IE blog later on 11/18 to get a recap of the chat with the top questions and answers. If you have suggestions for other chat topics you’d like to discuss directly with the engineers behind IE9, leave them in the blog comments.
UPDATE: Recap of the Twitter Q&A added
Thanks to everyone who sent in questions.
As we promised, we wanted to post a short recap of the chat. While the announced topic was JavaScript speed and the Chakra engine in IE9, we certainly answered a few other questions related to the browser. This was our first time trying out the Twitter Q&A format and we know there are some things we can improve on for next time.
In all we answered 37 questions over the course of 2 hours. We know we weren’t able to get to every question, and hope to answer some of those topics in future chats. A couple of the questions require more than 140 characters, and we plan to address these through upcoming blog posts both here on Exploring IE and through the IE blog on MSDN.
To see how it all went down, just search Twitter for the hashtag #IE9. You can also follow us on Twitter at @IE to see our tweets and updates.
Here’s a few of the Qs and As:
Q: getify #IE9 @IE @IETeam will IE9 get better support (like chromeless windows, desktop notifications, etc) for pinned sites on taskbar?
A: @getify IE9 already supports desktop notifications. See here http://bit.ly/bcj7P4 . See for an example http://bit.ly/bshOwg #IE9 ^AS

Q: FremyCompany: @IE How does #IE9 Dead Code optimisations (sic) impact real websites? If a code is not useful, the original website was not well engineered
A: @FremyCompany We've crawled real web sites to understand what kind of code they contain. Choosing to put deadcode optimizations in was based on our findings.
Q: GagaMonster013: @IE #Chakra Please can you add a new feature: when hovering over a tab in #IE9 can the 'exit' button appear. it enhances productivity
A: @gagamonster013 Great feedback. Submit it through MS Connect or Alt-X ^AS #IE9
Q: adamterlson: @IE #IE9 Has JS performance improvements reached the point of having no practical difference? What's the next big area of focus? GPU usage?
A: @adamterlson We are preparing for the JS apps of tomorrow. We're going to continue to push performance across *all* subsystems #ie9
Q: _raider5: @ie: Can #Chakra provide a script based method (host independent) to opt-in to a specific engine e.g. ScriptEngine.set('5.8')? #ie9
A: @_raider5 Use IE9 docmodes to cntrl JS functionality bit.ly/aVQmRL IE9Stds has ES5, IE8/IE7/Quirks maintain compat w/IE8 ^GS #ie9
Again, thanks to everyone who submitted questions. If you haven’t done so yet, check out Platform Preview 7 we released on Wednesday 7. And you can still check out the IE9 beta and some great real world sites.
1. Tabbed browsing is an integral part of Web-browsing and Without tab management IE is not good for tabbed Browsing
Opera recently implemented Tabstacking in their v 11 beta .. its a good feature .. I think it would be great if IE implemented it too albeit with some improvements like colored stacks etc...
2. Also please provide some sort of visual feed back to show if the page has loaded or not .... please .... this is a must in 3rd world countries where the net connections are not so stable
Please look into these matters and thanks for showing the transfer rate in the download manager :)
