Memory management is Java’s strongest suit and one of the many reasons developers choose Java over other platforms and programming languages. On paper, you create objects, and Java deploys its garbage collector to allocate and free up memory. But that’s not to say Java is flawless. As a matter of fact, memory leaks happen and they happen a lot in Java applications. We put together this guide to arm you with the know-how to detect, avoid and fix memory leaks in Java.

Using Node.js as a JavasScript runtime has its advantages. However, it requires significant maintenance to keep it working as expected. Here are the top metrics you should monitor for Node.js performance measurement analysis. Application programming interfaces or APIs that use the Node.js runtime environment are scalable. Node.js is asynchronous and event-driven, which means the application can handle multiple connections at the same time.

The Java Persistence API (JPA) is used in most Java applications to interact with a relational database. One of its most popular implementations is the Hibernate ORM, because it uses object-relational mapping to abstract database interactions and makes implementing simple CRUD operations very simple. But this abstraction also has its downsides. Hibernate uses a lot of internal optimizations and hides all database interactions behind its API.

Performance profilers mainly aid developers in analyzing the performance of applications. The purpose is to improve poorly performing sections of code that make up the functions of the application. When you say performance profilers, common names that come to mind are Visual Studio performance profilers and Prefix by Netreo. In this article, we will focus on the specific Visual Studio profiling tools for memory and CPU usage.

Web application monitoring tools can keep your business afloat. Period.  Imagine this. You’re about to run a crucial end-of-season sale on your website. You’ve sent your emails, run social media campaigns, paid for advertisements, and stocked up your inventory; you are all set to let the cash register ring.  However, on D-day, your website goes down. It’s unable to handle the incoming traffic or is simply down because of technical glitches.

Application server monitoring metrics and runtime characteristics are essential for the applications running on each server. Additionally, monitoring prevents or resolves potential issues in a timely manner. As far as Java applications go, Apache Tomcat is one of the most commonly used servers. Tomcat performance monitoring can be done with JMX beans or a monitoring tool such as MoSKito or JavaMelody.

Commonly, your website or app functions perfectly until you release it. During testing, you might seem to have control over everything. But, sooner or later, you will face some challenges. In fact, it is totally normal when something goes wrong. The most important thing is how you settle these problems. In most cases, issues with availability alerts and users’ complaints can be addressed by the means of IIS logs. IIS logging will provide you with the necessary data to deal with a breakdown.

As developers, we would rather be writing code all day than doing anything else. Especially meetings or fighting production problems. Unfortunately, both are part of the job. All developers need to understand the basics of web performance monitoring. It won’t help you get out of meetings, but it will help prevent production fires and put them out faster. Although, I guess it might also help you avoid meetings about production problems.

As you develop your software, you want it to work well, not only on paper but also as the actual users interact with the application. The way to create quality software that is easy to use and bug-free is with end-to-end testing.

No matter what you’re coding, there’s always room to optimize your code and improve performance. This can be a painstaking process, and if you’re going over your code line by line you’d better cancel all your plans and forget about getting any sleep! Fortunately, there are better ways to examine and optimize your code. A JS profiler is an efficient tool to help you understand your code better – effectively finding, pinpointing and optimizing bottlenecks in your code.
