Hello guys, if you have been doing Java development for few years, then you know that Performance is the key for any Java application. As a senior Java developer, one should know how to improve the performance of Java applications and understand memory management and garbage collection, which often causes Performance in Java applications. These are some advanced skills that take some effort to develop. It doesn't come by default even if you have been programming in Java for years, as most people don't touch these topics. Many of them are afraid or take the performance tuning work and always look up to the most senior or brilliant developers in their team.
Since many of my readers asked me about how they can improve their Java performance tuning skills, I will share a couple of the best online courses you can take to learn Java performance tuning. This is a continuation of my previous posts for experienced programmers like advanced Java books and advanced core Java courses.
These courses will teach you what every experienced Java professional should know about memory, garbage collection, VM tuning, and avoiding memory leaks.
Since many of my readers asked me about how they can improve their Java performance tuning skills, I will share a couple of the best online courses you can take to learn Java performance tuning. This is a continuation of my previous posts for experienced programmers like advanced Java books and advanced core Java courses.
These courses will teach you what every experienced Java professional should know about memory, garbage collection, VM tuning, and avoiding memory leaks.
You will learn about tools like memory analyzers, Profilers like JProfiler, VisualVM to learn and understand how to monitor the performance of Java applications, how to check GC logs, how to check if there is a deadlock or thread contention, and how to read thread dumps to understand what's going inside your Java application.
You will also develop skills to think in the right direction, like Is your Java service slower than you would like? Are they consuming too many system resources or lagging in Performance as load increases? Unless you question yourself and develop this thinking, it won't be easy to find the root cause of performance degradation and fix that.
Java applications can often suffer from memory problems like OutOfMemoryError and excessive GC logging, making your application slow. Still, you need experience and knowledge to figure out as there are too many things to know, like data increase, DB is blocking or slowing down, Linux machine has resource issues, or it is your Java code or JVM settings. These courses will show you how to fix them using freely available tools.
In this course, you'll first learn what can cause performance issues in Java applications like threads, memory, Garbage collection, and how to resolve them.
It will also teach you some of the best practices available to Java developers at design time, like making good coding choices for optimal performance.
We'll learn about various ways that you can configure the Java virtual machine to provide better performance at run-time. And we'll be diving deep into how the virtual machine manages memory and the garbage collection process.
Along the way, we'll be learning about the Just In Time compiler, performance testing and benchmarking, decompiling bytecode, using the GraalVM as an alternative virtual machine, and more. In short, one of the best course for experienced Java developer who is looking to take their skills to the next level.
In this course, you will learn all the essential tools you need to troubleshoot Performance and memory-related issues, thread-related problems, and JVM-specific things. As I have said before, tools are necessary because a Java developer is as good as its tools. If you don't know how to profile your Java application, you will never know which object is taking all the memory and the bottleneck in your code.
Similarly, if you can't read the thread dump, you don't know where exactly your program has stuck. Are they waiting for the Database to respond or another server or waiting for some file lock. If you know the right tool, you can troubleshoot quickly and efficiently.
The good thing about this course is that it is designed to teach you "how to fish." Instead of memorizing classes, libraries, or Java APIs, you will learn the fundamentals of concurrent programming, starting from the complete basics all the way to the very advanced topics in multithreading.
In this Udemy course, you'll learn what kinds of performance problems are possible in Java and how to avoid them. You will also learn how to use Java's tools and library to write high performance code using multithreading and concurrency.
