title: Is there any limit on number of html elements, that browser can display without problems?
body: <p>Basically I've got a huge table, which gets even bigger as user scrolls down (auto preloading subsequent rows). At some point browser becomes sluggish, it starts to hang for a moment as I click around or try to scroll and more sluggish it becomes, the more rows it gets. I wonder if there is any limit on number of elements that page can hold? Or maybe it's just my javascript leaking somewhere (although I've got only one event handler, attached to the tbody of the table - and a script that parses bubbled mousedown events).</p>
  
  <p><strong>Update:</strong> Delay becomes noticeable after a thousand of loaded rows. The speed of scroll itself is pretty bearable, but for example highlighting of the clicked row (with the help of single event handler on tbody) is painful (it takes at least 2-3 seconds and delay grows with the number of rows). I observe delay on all browsers. It's not only me, but almost everyone who visits the page, so I guess at some extent it affects every platform.</p>
  
  <p><strong>Update</strong>: I came up with simple example here: <a href="http://client.infinity-8.me/table.php?num=1000" rel="noreferrer">http://client.infinity-8.me/table.php?num=1000</a>  (you can pass whatever number you want to <em>num</em>), basically it renders a table with <em>num</em> rows and has a single event handler attached to a parent table. I should conclude from this, that there actually is no noticeable dropdown in performance, caused by number of child elements. So it's probably a leak somewhere else :(</p>
