Tips to improve performance of Java web applications

Java is a platform-independent language, offers a user-friendly interface and portable in nature. It is also an Object-Oriented programming that, allowing us to build real-world scenarios. Java includes a built-in multithreading feature that is extremely beneficial to the overall performance of any application. Because Java allows for distributed programming, it is popular among programmers. It also offers garbage collection that is automated. All of these features makes Java as a powerful programming language, but sometimes Java getting slow in its performance. In this article we are going to discuss how to improve the performance of a Java web application.

1. Upgrade to the most recent stable Java version

Every new version of Java has brought with it performance enhancements. To take advantage of these speed enhancements, make sure you’re using the most recent stable release of Java. Benchmarks show that adopting Java 11 instead of Java 8 improves performance by 5 to 16 percent.

2. Clean up your code and rewrite your algorithms

Clean code is simpler to maintain, modify, read, and enhance, and rewriting your algorithms to reduce the number of tautological function calls.

3. Avoid Database Connection Delays

Database connection pools are now used in the majority of commercial web applications. It’s well knowledge that the time it takes to create a connection can be longer than the time it takes to run a query after it’s established. As a result, most web applications now employ connection pooling to access databases. A set of database connections is pre-established, and programs obtain connections from the pool, utilize them, and return them to the pool. Applications save on database overheads and enhance their replies to end users by reusing connections for numerous queries.

4. When feasible, avoid recursion

Recursion is a necessary evil in some circumstances, but it should be used rarely.

5. Upgrade system hardware

Poor application performance may not be due to bad code or techniques, but rather to the system on which the program is operating.

6. Increase LAN and WAN bandwidth

Not all functions interact with local hardware; if your program communicates with external systems, it’s possible that your core network is at fault.

7. For increased performance, use StringBuilder

Strings are almost unavoidable in most applications, but the “+=” operation is slow.

8. Memory management can be influenced.

Although accessing heap memory is preferable than using the stack, it is occasionally unavoidable.

Memory availability is a major performance issue since a lack of memory will slow down all of your programs, and Java applications are particularly memory-intensive.
