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.
The Concurrent Mark Sweep (CMS) GC algorithm is deprecated in JDK 9 to simplify the GC code base and promote faster development. Users can switch to G1 or Z GC algorithms for improved performance or continue with CMS if it meets their needs. Each application's requirements should guide GC selection and performance evaluation.
