Question: Why is the action class is singleton in nature? Isn't this creates a bottleneck for the requests?

Answer: No it won't create a bottleneck as each request will be processed in separate thread. If would have created bottleneck it create separate instance for each request.

We just have to make sure that we are not using any instance variable in execute method.
