X-UA-Compatible=IE8 and doctype make IE8 search function extremely slow on larger tables
===

I noticed that when you have a rather large table (few thousand rows), the IE8 search function (Ctrl+F) becomes extremely slow when you use the doctype and set X-UA-Compatible to IE=8:

    <!doctype html>
    <html>
        <head>
            <meta http-equiv="X-UA-Compatible" content="IE=8">
            ...

Currently we have no way to decrease the size of the tables. Also, removing or changing the doctype or X-UA-Compatible messes up the layout of the page, so that's no quick solution either.

Does anyhave have any other ideas how to make the IE8 search function quicker?

To show the difference I created two test files that you can try (in IE8):

- <http://playground.steven.comprise.com/ie8/fast.php>
- <http://playground.steven.comprise.com/ie8/slow.php>

fast.php is the one without doctype or X-UA-Compatible. In this file the search is fast!
slow.php uses both the doctype and the X-UA-Compatible, so we want search in this file to become equally fast as in fast.php

Ideas?
