Another factor responsible for slowing down Java's performance, besides the I/O problem discussed above, is the synchronized statement. Generally, the overhead of a synchronized method is about 6 times that of a conventional method. If you are writing an application without multithreading -- or ...
Back to top Issue #3: Processing Data in the Database Another common source of performance problems is that we, as Java developers, tend to implement all the logic of our application in Java. Don’t get me wrong, there are lots of good reasons to do it this way. But there can also...
You may use connection pools, thread pools, queues and many other mechanisms to gain performance. And probably during tests, all these does very well for you, and your application operates as smooth as butter. But leaving any of these unbounded is asking for trouble. As a best practice cap ...
These application performance metrics, commonly known askey performance indicators(KPIs), are a quantitative measure of how effectively the organization achieves its business objectives. Capturing the right metrics will give you a comprehensive report and powerful insights into ways to improve yo...
How to improve program performance It is not an exaggeration to write a book about improving performance. Here are some of the most commonly used points: (1) Slow SQL If the response time of the general program is longer, you can first look at the slow SQL. ...
1. Reduce Application Size One of the easiest way to improve yourandroid app performanceis by reducing the size of your application. Users in emerging markets, whether devices are connected to 2G/3G networks or are connected to a pay-by-the-byte plan, frequently avoid downloading applications ...
Whether you’re a beginner just starting with Java or an experienced developer looking to improve your skills, this post will provide the foundational knowledge you need to understand threads and use them effectively in your projects. Introduction to Threads in Java Life Cycle of a Thread in ...
The JVM uses threads to execute every internal and external operation. As we know, the garbage collection process has its own thread, but also the tasks inside a Java application create their own. During its lifetime, the thread goes through avariety of states. Each thread has an execution ...
