title: How can I increase UITableVIew's performance?
body: <p>I have a multithreaded app that has a table view. It does data gathering in the background on a different thread. The problem is, when the user scrolls the table, the data gathering slows by a whopping 75%. And there's a lot of data to gather, so I want to have table scrolling reduce data-gathering speed by no more than 15% if that's possible.</p>
  
  <p>Is there perhaps a way to make the TableView only redraw when the user takes their finger off the screen? Don't worry about user experience, let me worry about that. If you have any ideas at all that could speed it up, I'd like to hear them.</p>
