Rightly termed, the “Queen of hill stations”, Qotty also known as Udhagamandalam is nestled in the lap of luscious Nilgiri or Blue mountains. Situated at an altitude of 2,240m above sea level, Ootty provides a perfect respite for families. Ootty is a hill station strewn with lakes, streams, gardens and colonial architecture.

You probably know the mantra that allocation is cheap. It usually is true, but devil is in the details. In your use case object allocation may impact processor caches evicting important data; burn CPU on executing constructor code; impact rates of object promotion to old generation and most importantly increase frequency of stop the word young gen pauses.
This presentation is for you if you are working on a Java based services that need to handle more and more traffic. As number of transactions per second rises you might hit performance wall that are young generation gc stopping whole application for precious milliseconds.
This presentation focuses on optimising object creation rate when dealing with seemingly mundane tasks. I will show few examples of surprising places in JDK and other libraries where garbage is created. I will explain how New Gen GC collection works and what costs are related to it. We will se escape analysis in action. Finally we will conclude that controlling allocation is the concern of library writers so that we can easily implement performant code without doing premature optimisations.
