JVM Tuning settings, the ultimate list

Let us begin with the very basic question, why do we need our JVM tuned up? And what exactly is JVM.

JVM, is the instance of Java Runtime Environment, which comes into action whenever you run your application

So, in order to make sure JVM runs fine we require that there is enough space for JVM to run programs. And hence we require timely check on the performance factors and space allotted to the JVM.

The crux of the matter: Heap and Garbage Collection

Key to Optimization: Algorithm and Analysis

Every problem has solutions but the most important thing is to find the solution that best fits that scenario. So as we take a dig inside the algorithms and techniques we will investigate how we can analyse the complexity and conclude the correct optimized solution.

Let us begin with a simple example and try to find the time and complexity.

Example : We need the sum of n natural numbers starting from ‘a’ and ending at ‘b’. Read More »
