What is the difference between Shared URLSession and URLSession with default configuration?In my app i was using URLSession.shared to send a request to server. Now i'm trying to change it to URLSession.init(configuration: URLSessionConfiguration.default).But if i use URLSession.init(configuration: URLSessionConfiguration.default) all my request are taking more time to load.Compared to URLSession.shared, URLSession.init(configuration: URLSessionConfiguration.default) is taking more time to load the request.(Shared Session is 5 to 10 time faster than URLSession with default Configuration).What is the Difference between these two methods?Why URLSession With Default Configuration is taking more to load the request?Note: I can't use the shared session for my usecase. I need to create multiple URLSession to send a request.
