Performance issue - style IE 5.5 vs IE 6.0

JavaScript performance issue

We develop web application (ASP, local language: JavaScript). IIS 6.0 render
the page based on the ASP script that represents some template of HTML
elements with defined styles:

<INPUT type=checkbox style='visibility: hidden;' id= 10 .... </INPUT>

Some validation and GUI visible logic is implemented via following principle
in JavaScript:

Get the element id = 10 from the document (example variable: objCheckBox10)
then: = "";

or vice versa: = "hidden";

This implementation has extremely lower performance in the MSIE 6.0 compare
to MS IE 5.5. The mentioned page works with hundreds elements. It means
internal interpretation has to be changed in IE 6.0 that works with styles.

Can anyone provide some relevant article, suggestion for the performance
fix, exist some registry key that fix this issue ?

Thank you


1. IE 6.0 vs. 5.5 vs. 5.0?

2. IIS6\IE performance issue versus IIS4\IE no performance issue

After upgrading IIS4 to IIS6 getting a page from the server is a pain when
running IE on Win2000. Same page is O'k if using the same version of IE on
WinXP. I noticed that IE takes 100% of processor for more than 20 sec when
opening the page on WIN2000. That was not a problem when web site was running
IIS4. It is a simple asp page - no graphics, just a table of data. What the
... IE is processing? It just needs to render the page. Again, on WinXP it is
not a problem. Changing IIS Isolation mode does not make any difference.
Anybody, any idea?
