Are you defining it with tableView:heightForRowAtIndexPath: in your DataSource? Apparently, that is a horribly slow method. If you keep all cell heights the same and use the property rowHeight - you'll find that reloadData is fast, even with thousands of rows.

I was more than happy to write it up - I figured someone else would run into the same issue I did. Glad it was useful!
