title: is too many element in the HTML can affect the page performance?
body: <p>i wonder if there's a difference between 
  1.) 10,000 tablerow which is visible
  2.) 10,000 tablerow which is hidden using display:none</p>
  
  <p>what i want to know is that. if all 10,000 row is visible on the page, could it cause the page scrolling to lag?</p>
  
  <p>but if i hide for example the 9000 of them. could this reduce the lagging? Thanks guys. </p>
