title: clientWidth Performance in IE8
body: <p>I have some legacy javascript that freezes the tfoot/thead of a table and lets the body scroll, it works fine except in IE8 its very slow. </p>
  
  <p>I traced the problem to reading the clientWidth property of a cell in the tfoot/thead... in ie6/7 and FireFox 1.5-3 it takes around 3ms to read the clientWidth property... in IE8 it takes over 200ms and longer when the number of cells in the table is increased.</p>
  
  <p>Is this a known bug ? is there any work around or solution ? </p>
