What is cip.readRetries?

cip.readRetries (CipReadRetries) is the number of times Swarm nodes retry a failed read to another Swarm node.  Setting this to zero means that we only try to read a missing stream once. 

This might be beneficial if your application's priority is speed of a returned response.  In other words, if you need to quickly respond with a 404 rather than a more accurate response that a longer wait might give you.
