5 tricks for better java performance

Java is the programming code used most frequently by software developers. Java is owned by oracle and it is not under free license. But users can easily obtain java for free through open JDK. This makes oracle java one of the free open source projects. Java development team that works with this code uses it to create high quality software. In recent years, java has taken the market from C++ and other such programming codes. However to make your java codes the best, you need to be fully aware of how it works. For optimization a thorough knowledge and some tricks are essential. In the following article, we will provide you with some trucks to optimize your java performance.

1. Basics:

In order to optimize your java performance you need to be aware of certain things, such as garbage collection, operating system settings and virtual machines. Java has several tools that can help you better the performance or optimize the program. You will also need to acquaint yourself with java terminology in order to understand the platform better.

2. Java virtual machine:

The best way to optimize your program is for you to know more about java virtual machine or JVM. Understanding the operating system and its workings will also help you as no two applications are similar. You need to know your way around and figure out what’s best for you. The JVM distribution model deals with many JVM instances in your application. You can better performance by running multiple JVMs on one server or one JVM on multiple servers. It depends on you as to which you will choose. This method will give you more resources to work with and better performance.

3. Garbage collection:

To properly optimize your application you will have to deal with garbage collection, by figuring out the garbage collection complexity for your application. For optimizing developers generally, change garbage collection settings and do profiling simultaneously. Outliers are notorious for degrading performance and you have to work hard to find them. Understand your workload and optimize accordingly. Slowdown in every transaction can be very costly.

4. Java heap:

Java heap is important in memory requirement. The best practice is to allocate minimum memory heap then increase it after you keep testing. Mostly your program gets optimized by varying memory heap but it doesn’t work when there is a huge amount of garbage collection overhead.

Garbage collection keeps lagging performance, so tuning it is important to keep the heap allocation as desired. Developers can use heap size 1GB or 8GB.

5. Core app optimization:

We have discussed several ways by which you can optimize your java program. But the one we will discuss now is perhaps the best way to optimize java. It is called core code optimization. Sometimes it happens that the application does not respond to any tuning of memory heap changes or even garbage collection settings. Therefore you should try to make changes in the architecture. See how your application works and figure out algorithms to solve slowing down issues.

Java development team always keeps working to better their coding experience and they apply such methods as heap and CG tuning to optimize their application.
