How to Tune Garbage Collection in Java

DZone

APRIL 21, 2019

These pauses are sometimes called Stop-The-World pauses, and the minimization of them is the primary concern of GC tuning, as they can have a huge impact on the performance of a Java application. This is why garbage collectors must pause all application threads when performing certain tasks.

JUNE 17, 2020

Does every performance engineer need to know about how memory in Java works? To completely fine-tune the java performance bottlenecks for high performance my answer is YES. Java has automatic memory management, a garbage collector that works in the background to clean up the unused/unreferenced objects and free up some memory.

Java Performance Tuning: Adjusting GC Threads for Optimal Results

DZone

AUGUST 30, 2024

Garbage Collection (GC) plays an important role in Java’s memory management. It helps to reclaim memory that is no longer in use. A garbage collector uses its own set of threads to reclaim memory. These threads are called GC threads. Sometimes JVM can end up either with too many or too few GC threads.
