My Peers always force me to use Spring for creating new instance of any object. As per as my understanding, Spring provides a platform to manage the Business objects more efficiently. Spring makes the architecture more modular and more flexible.

There are some instances where I feel not to use spring bean, and go for general method of creating new objects. But, my peers always forces to do it by giving excuses of performance improvement. I never find any article related to spring where the factor of performance mentioned.

Question : 
If I am using spring beans for creating the object whether it improves the performance compare to creating new instances using "new" operator.
