  <p>as shown in the image , i have 250 child gameobjects with boxcolliders ( NGUI Buttons - to be more specific) under the &quot;LevelButtons&quot;</p>
  <p><strong>MY PROBLEM :-</strong></p>
  <p>with this much amount of game objects moving when i drag/pan &quot;YellowBoard&quot; , the responsiveness is very low.</p>
  <p>When i keep 100 buttons only, scroll view works fine. but as increase number of buttons scroll view gets more slower.</p>
  <p>can some one guide me what alternatives i can use to solve my problem. since i can't reduce the number of level buttons.</p>
