Video description
Based on the best-selling book, Java Performance LiveLessons covers the latest Oracle and third-party tools for monitoring and measuring performance on a wide variety of hardware architectures and operating systems. In these video lessons, Charlie Hunt provides viewers with an overview of a modern Java Virtual Machine, the critical performance statistics to monitor within an operating system, JVM, and Java application, an overview of how the HotSpot garbage collectors work, explanation of the garbage collection output produced by the garbage collectors, and a step by step approach to tuning a Java application.
