How will the case of lacking of additional autoreleasepool effect "memory" and "performance" in cocos2d-x?

I knew that cocos2d-x is designed and implemented with 1 autorelease pool inside, so there’s no additional or even nested usage here.

Anyway I also knew that in objective-c world especially in tight loop that creates lots of objects, we can create additional autoreleasepool to manage and release object from the scope and will better serve the good memory management.
