IE8 Performance

Google has commented on our IE8 Beta 1 improvements, and we've made IE8 even faster since then. Some of the tests we have done show pure JScript performance improvements up to 2.5 times. We also measured the performance gains on common Gmail operations, like loading the inbox (34%), opening a conversation (45%) and opening a thread (27%) compared to IE7. Thus far, tweaks to the JScript engine have contributed to improve IE8's performance on the SunSpider benchmarking suite by 400% compared to IE7.

The second area in which we are invested heavily in IE8 is in improvements to our memory usage. To date we have fixed just under 400 separate memory leaks in Internet Explorer. For users, these changes reduce the amount of memory consumed by IE, improve our startup times, speed up navigating between pages, and help IE remain stable for longer periods of time. As we started building IE8 it was clear that we could do more to take advantage of the increasing prevalence of high bandwidth connections. Two key improvements we made with IE8 were to unblock downloads in the presence of external scripts and to increase the number of parallel connections per server that we support.

All I say is thank god I have an image build for my OS because I would have been up ***t cr*** without a paddle, install MSIE8 and all went well untill I restarted and then started IE and all hell let loose. I'm running Vista 64-bit OS and although there is a download available for Vista 64-bit, it din't like me at all.

Missing this until the final build. as for performance did not have time to do anything with it because it messed up my OS and slowed everything to a halt after reboot and first start.

They really need to cut down on files size though...no reason a browser should be (up to) 80 freakin mb...and that was from the win98 IE 4-5 days, last time I used IE. I could only imagine what size it would be now. The more crap you get with it, the more chance of security holes.

Also, I know why it takes MS ten years to finish something. Have you ever called customer service? Talk to one person, they don't know answer, transfer you to another, do that 15 times and end up back to the person who originally answer'd the phone. I only imagine they do that with software....here you do it...no you... cause I dont know either.

I was an IE junkie for the longest time, until I got sick of IE memory leaks with opening too many windows (IE6+7) or too many tabs (IE7).

Hardcore IE junkies will bring up the age old FF/IE battle saying how IE is better than FF. Whether it is better or not is always up for debate. What is NOT up for debate is that FireFox completely changed the internet browser market in that it forced the Internet Explorer team to get off their asses and make improvements to Internet Explorer.

It is amazing to see the whole change in pace of Internet Explorer development:
Version 6 was released August 2001.
Version 7 was released 5+ years after that in October 2006.
Version 8, which I fully expected to take like 10 years the way Microsoft handled Vista, now looks like it will be released only 2 years after v7.

LOL, Even with all these javascript improvement, IE8 is still slower then Opera, Saferi 3, and Firefox 3.
So not to mention the upcoming TraceMonkey and SqurrielFish Improvement. IE8 is still slow.

Much like Intel like to boost about their IGP getting 2x Faster every generation. 2x Faster is nothing when your Javascript Engine is INCREDIBLY slow to start with.

Anyway it is still in beta and i hope IE8 can further trim the fat, and performance improvement.

Yes, toolbar customization is in - at least as much as I remember you being able to do in IE6 (you can add/remove buttons, and move the toolbars around). Having the much improved dev toolbar and JS debugger embedded is nice too. I'm liking the related tab highlighting, accelerators, and improved search (switching providers is now one-click away, gives suggestions, and searches your history) though I haven't really gotten the web-slices to work yet, they look like they'll be a useful addition. Being able to un-close a tab, and restore your tabs from the previous session are also welcome features - though nothing new to the browser world.

Got my hands on IE8 Beta 2 from Majorgeeks.com, and must say its a 10 fold jump over BETA 1. It's sooooooo much quicker on a 2mb connection, can't wait to get home and try it on my 20mb connection. Pages are rendering a hell of a lot quicker. It looks a lot more final now. The new look Facebook still needs IE7 compat, but thats easy enough to sort out through the Tools menu. Seperate tab for Safety now. This is def a keeper build.

Although it is nice having these browsers much faster there is so much more speed that can come from:

  • Designing a Website Properly
  • Optimising a Server
  • Indexing and Optimising a Database
  • Do Not Use Bigger or More Graphic Than Needed

These things would do more for webpage loading than any improvement to the browser.

I welcome any browser speed increase, innovation, competition.

Yes, Internet Explorer 8 has got several things Firefox has not, yes you can add to Firefox with third-party extensions, 98% of users (yes I made that up) would not know how to install an extension.

Maybe someone here can help me out.. seeing as I literally don't have time to go hunting.

What features of IE 8 are actually new.. meaning something that doesn't fit the category of "been there, done that".

400 known memory leaks.. yet only posts here at Neowin complained of FF's memory leaks.

Private browsing? So last year.... and now I hear that IE 8 is going to have it's own Bookmark Toolbar?? WOW what a concept that is..

Not trying to stir up too much... which around here, not that hard to do.. all you have to do is sneeze the fact you like something other than Redmond products and your fish bait.. but what is really "NEW" with IE 8? That isn't already available or has been, with either Opera, Firefox.. or even Safari?

Why does it matter? You've made your opinions clear, you don't like IE. That's fine, that's your opinion. But what is it about IE8 that you don't like? (Rhetorical question). Firefox and Opera pretty much do all those things, so you like them, right? If IE8 did the same, would you still dislike it so much?
Yes, they're playing catchup, yes, they're not being very innovative, but they sat on their arses with IE6 for years and this is the price they have to pay. Give them time to catch up with the competition before you go bashing them for not being innovative enough.
I'd rather have a product that did the same things as everything else, only better, than a product that tried and failed to do something new.

only the feature already stated on the first news about IE8 about each Tab having his memory space with not make the entire browser crashs in some java or flash websites is enough reason to use it

and yes, i'm a firefox user since 1.x and i'm glad about this news about ie8, even FF3 still is a memory hog and CPU cycles eater

but of course in the end about all that matters is the speed of the browser on the pages and if the pages are displayed properly, IE7 is way to slow in javascript, lets see if they improve it at the FF and Safari level

Think about what happens when you open a PDF in FF. The entire browser window freezes the **** up. With IE8, this may not be the case anymore, what with the seperate processes per each tab.

Perhaps Joe Wilcox should read this article. Then he could answer his own question of "Who cares" and maybe get something factually accurate in his moronic blog postings while searching for jobs postings at the local McDonald's.

i like it how the blog goes on about "new" feature of data uris which have been in other browsers for years.

like all these things, it will be interesting to see what the real world performance of the browser is.

Performance is one thing, but the most important thing for IE8's success IMO is whether its compliance mode will also work for IE6. IE7 compatibility was never a huge problem, IE6 is still a terrible headache for every web developer. The common excuse for keeping IE6 is that IE7+ will break a company's poorly coded webapps. Thus if IE8 would work with them, there would be no need for IE6 anymore. No IE6 = no need to develop for it = easier times for web devs/designs everywhere.

Nice! I'll be upgrading from IE 7 to 8 Beta 2 on this laptop. I got this laptop as new 3 weeks ago - decided to skip IE 8 Beta 1 as I have it on my desktop and server.

Can't wait to get Beta 2 and try out the "porn mode" feature, haha.

About time! I much prefer IE (and yes, partially due because i am used to it), but its javascript has always run rather poor...glad to see they are speeding it up!

Wow really nice! IE seems to often lockup its tabs or thirt party browser shells while loading multible sites, so any unlock and speedups helps.
The first beta was a bit buggy as image links had their click focus rectangle moved to the left.

And this would be why it is BETA. Beta 1 at that. Things are bond to improve as it goes thru the beta process

There's a term for people like that. IE8 could literally spew money at you and somehow Mozilla would still be "better".

To be honest, if that were the case, the natural psychological response would be "because Firefox doesn't need to bribe you to use it."

IE8 could go open source and Firefox could insert a mandatory ad banner pane and people would just say giving up some screen real estate is worth it to be able to use Firefox. These people are just that 'special'.

Such a shame. If a news article is posted about IE8's standards compliance or whatever, there's usually hundreds of comments bashing it, yet when a post is made about a genuine improvement to the browser, people don't seem to care.
Even though I'm a huge Firefox fan, I still appreciate knowing that other browsers are out there and giving Mozilla some good competition.

Good news, and IE8 Beta 2 will be out by end of August, at least what everyone has heard on many websites.

It is the end of August

(EduardValencia said @ #1.1)
What happened mate,this is good news!

IE8 is shaping up very well,hope they incorporate the download manager.


but, what is the performance boost in comparison with firefox3 ?

(Magallanes said @ #1.2)


but, what is the performance boost in comparison with firefox3 ?


Firefox 3.1, with TraceMonkey, is getting another huge performance boost...

(EduardValencia said @ #1.4)
Enough performance boost to calm down IE critics,and thus switiching to FF3 because of that reason.

Yes? or not?

The beta has just gone public and the IEBlog is commenting on a post beta build so it's probably too early to tell...

This is good news though - memory leaks in browsers are something I really hate and it's good to know that the JScript engine is being tweaked, with so many 2.0 sites around things have got to improve.
