title: JSF2 / Primefaces layout performance
body: <p>Right now I'm using a full page layout and p:layoutUnits and page composition in my webapp. I have a fixed header with a menubar, and a content layoutunit, and that's all. It was easy to set up, but in IE (7) when I navigate to a new page the whole page reloads (visibly), the header is cleared then loaded, and - even more annoyingly - the menubar is displayed for a second with all the menuitems visible.</p>
  
  <p>In other browsers this effect is not really visible, sadly, IE 7 is my target.</p>
  
  <p>Now I'm thinking about saying goodbye to p:layoutUnits and implementing the layout with simple css magic and fixed div for the header - would it improve display in IE? Is there anything else I can do to make it faster and smoother? I'd like it to look like the header is not changing at all, only the content.</p>
  
  <p>How about using <strong>iframe</strong>? Would it allow bookmarkable URLs?</p>
