Optimization

You want your instance pooling to be fast. That was the point of implementing it after all, right? So, let's make it fast(er)!

Scaling up the pool

The default size of the pool is 100. Depending on your use case, this will be way too little instances. Pass size = <n> to increase the default pool size.

Dynamic scaling

Pooler supports a form of dynamic scaling by using pool:Resize(newSize). This will automatically add or remove instances depending on on the new size. You can also get the current size by using pool:Size() to introduce some automatic scaling based on pool usage.

Using a different return method

If you're using BaseParts or Models with PrimaryPart set, then you should be using the cframe return method instead of the default nilParent return method. This will cause the parts or models to be CFramed away outside of the map rather than modifying the parent, which is a much more costly operation.

Disabling safety

The largest amount of time is dedicated to safety. If you know that your calls to Pooler are correct, you don't need to bother. When creating your pool, pass unsafe = true as an option to disable safety. This will speed up your pool drastically at the cost of being able to create some weird bugs if you don't check your code properly.
