    <thetext>Go to http://dglazkov.github.com/performance-tests/scroll-by-hiding-tables.html, click &quot;Go&quot;, then check/uncheck &quot;User overflow:hidden&quot; to see the difference in FPS.

Compositing shows the biggest hit:

Check &quot;Stacked tables using z-index&quot;, &quot;Use overflow:hidden&quot;, then &quot;Go&quot;, then check/unchek &quot;Use compositing.&quot;</thetext>
