title: In spring, is there a performance difference between prototype and singleton?
body: <p>When I using spring framework to write business code, I always use the singleton scope and avoid using the prototype scope. I think there is a performance difference between prototype and singleton. Because of the prototype scope, spring creates a new instance every call. And I think it is slower than using the singleton scope. Am I right? And am I giving too many considerations to the performance?</p>
