In computer programming, a Object pool is a software design
pattern. An object pool is a set of initialised objects
that are kept ready to use, rather than allocated and
destroyed on demand. A client of the pool will request an
object from the pool and perform operations on the returned
object. When the client has finished with an object, it
returns it to the pool, rather than destroying it. It is a
specific type of factory object.

Object pooling can offer a significant performance boost;
it is most effective in situations where the cost of
initializing a class instance is high, the rate of
instantiation of a class is high, and the number of
instantiations in use at any one time is low.
