How many times do we change the networking strategy of our application because a client or users said it is too slow? Networking is not completely controllable from the client side because too many external factors are involved in the process: proxies, web servers, service providers, DNSs, and so on. We cannot know if there is a problem in one or more of the elements of that chain.
