Java Performance Tuning Ed 1 Course Overview

Java Performance Tuning Ed 1 Course Overview

The Java Performance Tuning Ed 1 course is designed to equip developers and performance engineers with the necessary skills to optimize Java applications. The course covers the intricacies of the Java Virtual Machine (JVM) and its impact on application performance. Starting with an overview of JVM and a discussion on defining performance, it introduces a structured Performance Methodology to tackle performance issues methodically.

Learners will delve deep into JVM internals, focusing on Garbage Collection (GC) mechanisms and algorithms, and understand different types of GC collectors and their ergonomics. The course offers practical skills in monitoring and tuning the JVM using command-line tools and advanced utilities like VisualVM, Mission Control, and the Java Flight Recorder.

The curriculum also extends beyond JVM to address operating system-level performance monitoring, covering aspects such as CPU, memory, network I/O, and disk I/O. Additionally, attendees will master the use of various Performance Profiling Tools for CPU and heap analysis, which are crucial for identifying bottlenecks and enhancing application efficiency. With this comprehensive training, learners will be well-prepared to optimize Java applications for better performance and reliability.
