Java Application Performance is the practice of assessing and improving the performance of software applications developed in Java programming language. The performance focuses on the resource utilization, speed, scalability, and overall execution time of the Java application. The practice includes optimizing the code, JVM (Java Virtual Machine) settings, and other system-level configurations for serving high traffic, large data sets, and complex operations efficiently.
Certification in Java Application Performance validates your skills and knowledge in profiling, memory management, JVM tuning, and implementing efficient algorithms by using performance tools to analyze bottlenecks, and use best practices.
