   Hi, I have several "panel" sprites with have CCMenu's attached as children (which themselves contain lots of buttons).

   Since none of these can be children of a SpriteSheet, I'm concerned this affects performance.

   I have positioned them offscreen and set them to not visible when not in use. Should this be enough to stop them lagging?

   Thanks!

   What is the 'actual' observed hit on performance?
   How many buttons are we talking about?

   Each panel has a CCMenu with about 1-5 buttons, there are about 20 panels (and thus 20 CCMenus).

   I'm not 100% on how much of a performance hit it's having as it would take a lot of editing to remove them.

   Would all those Menu's likely be creating an issue? (even if the panels + buttons arn't visible)

   I have the same problem before. I have 50 buttons on screen. My frame rate was 25-30. And now is 60.

   My solution was make a for loop and then align them. Works fine for me.

   CCMenu *menuArray = [CCMenu menuWithItems:nil];
   [self addChild:menuArray];
   
   for(int x=1; x<=50; x++){
   				CCMenuItemImage *level = [CCMenuItemImage itemFromNormalImage:@"levels_background..png" selectedImage:@"levels_background_down.png" target:self selector:@selector(level:)];
   				level.tag = x;
   				level.position = ccp(level.contentSize.width, level.contentSize.height);
   				[menuArray addChild:level];
   
   		}
   
   		[menuArray alignItemsInColumns: [NSNumber numberWithInt:10],
   		 [NSNumber numberWithInt:10], [NSNumber numberWithInt:10],
   		 [NSNumber numberWithInt:10], [NSNumber numberWithInt:10], nil];

   hmmm, how would aligning button positions improve that?

   I think the improvement comes from storing the menus in an array and thus only accessing them when needed.
