The Java Concurrent Mark & Sweep (CMS) garbage collection algorithm aims to minimize pause times by marking and sweeping memory concurrently. Despite its benefits, CMS has been deprecated since JDK 9 and removed in JDK 14. This post discusses tuning techniques, JVM parameters, and advanced options to optimize CMS performance for specific scenarios.
Enterprises are unknowingly wasting millions due to ineffective garbage collection. This issue stems from automatic garbage collection in languages like Java, which pauses applications to clear unreferenced objects, leading to significant lost processing time. Effects include reduced throughput and financial losses, signaling a need for better garbage collection tuning and efficient coding practices.
