title: Vim Scrolling Slowly
body: <p>Vim is acting slow when I scroll. The cursor skips some lines when I'm pressing j/k continually.</p>
  
  <p>I'm using xterm and urxvt. In both vim acts like this.</p>
  
  <p>This happens locally, with small or big files. I do use Control + F/B they work just fine.</p>
  
  <p>EDIT: ttyfast in small files did the trick but in bigger is the same. When running without customization it goes allright.</p>
