ZGC, or Z Garbage Collector, is a modern garbage collection algorithm introduced in Java 11. It was designed to handle very large heap sizes with extremely low pause times. ZGC aims to keep pause times under 10 milliseconds, even with heaps sized in terabytes. For beginners, ZGC might sound complicated, but this article breaks it … Read more
The Concurrent Mark Sweep (CMS) Garbage Collector was a popular garbage collection algorithm used in the Java Virtual Machine (JVM) for many years. It was introduced to reduce long pause times caused by Full GCs. Although it has been deprecated in newer Java versions (starting from Java 9 and removed in Java 14), many applications … Read more
The G1 Garbage Collector (G1GC) is one of the most advanced garbage collection algorithms in the Java Virtual Machine (JVM). It is also called Garbage-First Garbage Collector. It was designed to handle large heap sizes and to meet the needs of modern Java applications. Introduced in Java 7 as an experimental feature and made default … Read more
The Parallel Garbage Collector (GC) or Throughput Collector is the default garbage collector used by JVM. The parallel garbage collector works the same as the serial garbage collector. The only difference between serial and parallel garbage collectors is that serial garbage collector uses a single thread for the garbage collection process while parallel garbage collector uses multiple threads for … Read more
Serial Garbage Collector or Serial GC is the most basic garbage collection (GC) algorithm used in Java. It works in a single-threaded way, meaning it uses one thread to perform all garbage collection tasks. During a GC event, your application pauses completely—this is called a stop-the-world pause. Although Serial GC causes these pauses, it’s still … Read more
