Does your game need good performance? Are you using an object pool for your objects?
You will then likely experience moderate to extreme performance improvement by recycling your objects!
Object recycling is the art of reusing objects instead of all the time creating new ones and destroying old ones. Each type of recyclable object gets its own dedicated object pool by the recycler.
Why is creating and destroying bad? Because it creates a lot of work for Unity and will decrease performance, especially when it has to take out the trash a lot (clean destroyed objects).
If you are using GameObject.Destroy(gameobject) in your code then you may consider object recycling.
The object recycler works by keeping track of your deactivated objects and making them active once a new objects are needed instead of creating a new one.
