<p>I am using the YUI layout manager which seems to work at an OK speed. However if the page contains a large <code>&lt;Table&gt;</code> with about 500 rows, the YUI <code>render()</code> function takes about a <strong>minute</strong> longer to run.</p>

<p>When I open the same page without the layout manager it opens in less than a second.</p>

<p>My <em>only</em> concern is with <strong>IE 7</strong>. I tried it on firefox and it only took about three seconds.</p>

<p>Any ideas on what is taking so long? Can I somehow tell the layout manager to ignore the table?</p>

I finally figured it out myself.
The trick is to hide the content that should be ignored by the layout manager.
Before calling
```
render()
```
set the
```
style.display = 'none'
```
for a tag that contains a large chunk of the page you don't need the layout manager to manage. Set it back to normal after with
```
style.display = 'block'
```
.
