For a first step, I'd watch the network using Fiddler, both for IE and for FireFox. See if there's a significant difference in the order of the resources they're loading, and the time it takes.

Also, since JavaScript is involved, it's possible that some of the page resources are being loaded by JavaScript code that is running differently on IE than from the other two browsers.

After analyzing things, you'll have a better idea of whether IE is slow, and where it's slow.

It took 10 seconds for me to load your page in Firefox. The difference you see is probably a difference in cacheing between different browsers - try clearing your cache in firefox (Tools>Clear Private Data) and you will probably see the same slowness.

To speed up initial page loading for the first visit (which will probably be more important to you) try using <a href="http://developer.yahoo.com/yslow/" rel="nofollow noreferrer">YSlow</a> to profile your site.

These are the points where YSlow says you should improve:

YSlow:
Grade E, Overall performance score 55/100

Divided into grades:

<ul>
<li>F:

<ol>
<li>Make fewer HTTP requests

<ul>
<li>Use a Content Delivery Network (CDN)</li>
<li>Add Expires headers</li>
<li>Compress components with gzip</li>
<li>Put JavaScript at bottom</li>
<li>Configure entity tags (ETags)</li>
</ul></li>
</ol></li>
<li>E:

<ol>
<li>Avoid AlphaImageLoader filter</li>
</ol></li>
<li>C:

<ol>
<li>Reduce DNS lookups

<ul>
<li>Minify JavaScript and CSS</li>
</ul></li>
</ol></li>
</ul>

You can read about how to rectify these problems <a href="http://developer.yahoo.com/yslow/help/#guidelines" rel="nofollow noreferrer">here</a>. I'd pay special attention to the AlphaImageLoader-warning, since that is specific to IE. It also causes several requests and is slow, especially when there are multiple images that needs to be filtered. You could try to use .gif-images instead since IE can handle them natively.

Google's Page Speed gives you the following:

Total score: [Score: 17.9%]

<li>Leverage browser caching [Score: 0%]</li>
<li>Combine external JavaScript [Score: 47%]</li>

You can read about Google's best practices <a href="http://code.google.com/intl/sv-SE/speed/page-speed/docs/rules_intro.html" rel="nofollow noreferrer">here</a> and learn how to improve load times and site efficiency. Note that Google has some practices that are not considered good practices in every day web development, such as not linking in an external stylesheet (it's an extra request), but most sites will NOT suffer from linking in an external stylesheet. So you'll have to consider every "rule" and ask yourself if that is something you like and would benefit from.

blocks|key|56988|text|我发现IE和FF之间的主要问题是：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|56989|即:首先加载完整的内容(文本、图片、CSS、JS)，然后显示页面。|56990|FF+:首先显示页面，然后加载显示页面的文本，然后加载其他来源(图像、CSS、JS)|56991|这就是为什么FF在显示页面时速度更快的原因。|56992|雷加尔德|56993|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|M|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|N|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|O|8|@]|9|@]|A|$]]|$1|H|3|I|5|6|7|P|8|@]|9|@]|A|$]]|$1|J|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|K|$]]

The main Problem I found between IE and FF is :

IE : First loading the full content (Text , Images, CSS , JS) Then Display the page.

FF : First Displaying the page then loading the text Displaying the page Then other sources ( Images , CSS , JS)

So this is the reason why FF is faster in displaying the pages .

Regaerds

When I load the <a href="http://www.sparkx.com/home" rel="nofollow noreferrer">frontpage of the website I work for</a> in IE it takes about 7 or 8 seconds to load fully (meaning, the "<code>Waiting for</code>" and "<code>(x items remaining)</code>" disappear and change to "<code>Done</code>".

The exact same page takes about half the time in Firefox and Google Chrome, and I just can't figure out what's causing the difference.

Is this just general IE slowness, or is it something more? The server side script itself takes about 45ms to run, so that's not the problem, however I do wonder if our URL rewriting may be a cause. Then again, why only IE?

Loading of pages in IE very slow compared to other browsers

当我在IE中加载时，大约需要7或8秒才能完全加载(意思是，"Waiting for“和"(x items remaining)”消失，并更改为"Done“。在Firefox和Google Chrome中，完全相同的页面花费了大约一半的时间，而我就是找不出是什么导致了差异。这只是一般的IE缓慢，还是有更多的原因？服务器端...
