Disappointing story on memory optimization

Disappointing story on memory optimization

Not all stories need to be success stories. Reality is also not like that. We would like to share a true, disappointing story (but a phenomenal learning experience) that may be beneficial to you. 
This is a story about optimizing memory utilization of a web application. This application was configured with a lot of memory (4GB) just to service handful of transactions/sec. Thus, we set out to study the memory utilization patterns of this application. We captured heap dumps of this application using ???jmap??? tool. We uploaded the captured heap dump to HeapHero tool. HeapHero is a heap dump analysis tool just like Eclipse MAT, JProfiler, Yourkit. HeapHero tool profiled the memory and provided statistics on total classes, total objects, heap size, histogram view of large objects residing in the memory. On top of these traditional metrics, HeapHero reported the total amount of memory wasted due to inefficient programming practices. In modern computing, considerable amount memory is wasted because of inefficient programming practices such as: Duplicate object creation, suboptimal data type definitions (declaring ???double??? and assigning only ???float??? values), over allocation and underutilization of data structures and several other practices.

What is Metadata?

What is metadata? Well, It’s an odd concept to wrap your head around. Metadata is essentially the secondary layer of data that tracks details about the “regular” data. The regular
