Tips to Enhance Java Applications’ Performance

Anyone who is involved with app development has most likely also used, Java. While this programming language is over two decades old, it continues to be one of the most widely used languages in the development world. In fact, according to statistics, roughly 10 million developers across the globe harness the prowess of Java to create applications aimed at addressing needs and issues in a variety of facets of daily life.

So even though Java it is used by such a large number of developers and big companies, the fact remains that a lot of them often struggle to optimize their Java app’s performance. A vital component of the development process, the ability to glean better performance from the app can pretty much decide how well your customers receive the app. So, no matter if you are planning to develop a Java app or are already in the process of creating one, use the following tips to enhance your application’s performance significantly.

1. One step at a time: After the test suite and profiler are put together, the developer needs re-examine the issues that generally present themselves at this stage. The best way to boost your app’s performance at this point is to tick off the most pressing problems first. Instead of trying to address all issues in one go, start with the significant performance-related challenges. Once they are resolved, you can move on to the issues lower on the priority ladder.
2. Bid farewell to old references: Obsolete object references are the ones that developers retain for whatever reasons but never use them. It, in turn, keeps the object it refers to from qualifying for garbage collection. Also, where does that lead us? Down the memory leak lane. The ideal method for doing away with an old reference is dropping it out of scope.
3. Avoid recursive code: While specific languages encourage the use of recursive code to facilitate the optimization of tail-recursing into the iterative code, let’s say that it is typically not the wisest idea to do so especially with Java apps. Why? Because though a capable compiler ought to identify when a small change in the algorithm kills a tail-recursive branch, it is not assured. It, in turn, results in needless spending of stack frames. What you can do, instead, is to leverage local variables to dodge recursion issues.
4. Keep concurrency in check: Multiple programs running in parallel takes a toll on the performance. Sure, there is the option to use concurrency across threads to generate the scope for parallel processing, but using it to attain better performance for your Java app can prove to be a tricky endeavor. However, here’s a tip: Ensure that you correctly use the data access framework since it stands to enhance the performance of the data access layer, which, in turn, helps optimize the app’s performance.

It is understandable to want to ensure that your Java app delivers the best possible performance. Moreover, if you’re going to put your app’s real potential to use, our advice is that you hire Java programmer — one that has ample experience — to identify and implement improvements that will boost your app’s performance.
