Parallel Garbage Collector (GC)

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

Parallel Garbage Collector

Parallel Garbage Collector (Parallel GC) is a Java GC algorithm designed to speed up memory cleaning by using multiple threads. Unlike Serial GC, which pauses everything and works single-threaded, Parallel GC divides the work across threads to shorten pause times. It focuses on high throughput, making it suitable for apps that can tolerate occasional pauses … Read more

Serial Garbage Collector (GC)

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

Performance Testing – System Failures & Losses

If we dig down the history, many incidents occurred that led to system failures and business losses in terms of money and brand value. Among them, some could have been avoided with continuous server monitoring and proper performance testing. So, let’s discuss what history says to us and what we can learn from it. As … Read more
