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
The Serial Garbage Collector (GC) is the simplest and oldest garbage collector in Java. It derives its name from performing all its work on a single thread. Main Operation Single thread to perform Garbage Collection (GC) How does Serial GC work?

As you know the Garbage Collection shouldn’t happen too soon or too late, because in both cases the performance of the system gets affected. A delay in GC cycles results in memory leakage, whereas too many GC cycles reduce system performance and increase CPU usage. Along with this we also need to understand how much … Read more
When it comes to the memory management of a software application, garbage collection is crucial. Actually, the memory of unused or unreferenced objects is recovered by a Java program called Garbage Collector. It means that, like other Java codes, the GC executes when a certain condition, such as memory fullness, is met. GC affects the … Read more
Before discussing the type of garbage collector, it is important to understand some basic terms related to it. Type of Garbage Collector: 1. Serial GC: Serial GC is designed for single-threaded environments. It uses just a single thread for garbage collection. As a result, this GC implementation freezes all application threads when it runs. This leads … Read more
