Java Concurrent Mark & Sweep (CMS) algorithm operates by dividing the garbage collection process into multiple phases, concurrently marking and sweeping the memory regions without a significant pause. While its design brings benefits in terms of reduced pause times, it... Continue Reading →
Shenandoah GC aims to reduce pause times in Java applications by performing garbage collection concurrently with the application threads. At the heart of Shenandoah's innovation is its region-based memory management. The heap is strategically divided into regions, allowing garbage collection... Continue Reading →
Parallel garbage collector (Parallel GC) is one of the oldest Garbage Collection algorithms introduced in JVM to leverage the processing power of modern multi-core systems. Parallel GC aims to reduce the impact of GC pauses by utilizing multiple threads to... Continue Reading →
When you tune Garbage collection performance, you are not only improving Garbage collection pause time but also the overall application's response time and reducing cloud computing cost. Recently we helped to tune the Garbage collection behavior of a popular application.... Continue Reading →
I have heard a few of my developer friends say: “Garbage Collection is automatic. So, I do not have to worry about it.“ The first part is true, i.e., “Garbage Collection is automatic” on all modern platforms – Java, .NET, Golang,... Continue Reading →
