Consider the following a webpage:

<HTML>
 <HEAD>
<SCRIPT>
 function countit()
 { testref=document.getElementById('test');
   for (i=1; i<=1000; i++)
     testref.inny.value=i;
 }
</SCRIPT>
</HEAD>
<BODY>
<form id=test>
<input id=inny size=10>
<input type=button value="count now" onclick=countit()>
</form>
</BODY>
</HTML>

In Mozilla you will see a counter going rather slowly from 1 to 1000. In IE
you will only see the figure 1000 after a short wait.

I suspect that this is major reason why Mozilla is so slow when you have
many input fields.

Does anybody know why this is made so?
