In this example code, I would be using these sprites for a menu button
```
[CCSprite spriteWithFile:@"myFile.png" rect:CGRectMake(0,0,10,10)];
[CCSprite spriteWithFile:@"myFile.png" rect:CGRectMake(10,10,10,10)];
[CCSprite spriteWithFile:@"myFile.png" rect:CGRectMake(20,20,10,10)];
```
Would "myFile.png" be loaded into memory 3 times in order to extract the rect?

Would it be more efficient to use a Zwoptex/CCSpriteFrameCache and use spriteWithFrameName:?

In some cases, I'm loading 36 sprites at once in this fashion, so I'm just trying to figure out the best way to do it in 0.99.5.

The texture cache looks after making sure a texture is loaded once only, so only on the first call would anything be loaded into memory - the rest use references to the texture id created when the first is loaded.

Having said that, you'd no doubt find it easier to use Zwoptex/CCSpriteFrames - it makes for a lot cleaner code that's easier to maintain (ie if you make a change to the layout of your textures).
