Pooling on a client side is becoming more and more a standard in many new libraries across all languages. You should always use client pooling, at least in stable code/components (there is no need to go through it if you are hacking together a script).

However client pooling can only optimize the single client that it runs on. Server side pooling allows it to optimize all the connections. If you are running a small deployment with couple of clients, then you truly don't need to use any server side pooling. Not that you won't benefit from it, but it may be a bit more hassle than needed.
