But that book says it is to reduce the memory footprint  ?

Even other sources such as this for example :
http://serverfault.com/a/487473

Say not using it would increase memory I would rather have low memory impact
especially in a scenario where there are lots of requests that will quickly
fill up the memory the less it uses and more memory available the better.
