Imagine this. A small script is fetching product data from an API, adjusting the format, sending it forward. Nothing fancy. Part of your usual flow. Then, without any warning, the JVM’s garbage collector stutters. Everything freezes in an instant while you’re focused elsewhere. The impact hits late. Imagine your app’s memory divided into two areas. ...

Java garbage collectors play a critical role in shaping application performance, directly influencing latency, throughput, and infrastructure efficiency. As JVM-based systems power modern production workloads, from microservices to large-scale enterprise platforms, memory management behavior becomes a key determinant of system stability. While the J...

Garbage collection tuning is one of the most underappreciated, high-impact performance optimization techniques for JVM-based systems. Although Java’s automatic memory management makes development easier, the default garbage collection settings are tuned for general-purpose workloads, not the production systems with hard latency and throughput requir...

Monitoring garbage collection (GC) is an important part of Java troubleshooting and performance tuning. Since it’s not practical to scroll through thousands of lines of logs, we need a good GC log analyzer to keep tabs on whether the system is tuned to best advantage.

There are several excellent GC analysis tools available. Some are commercial, some are open source....

In Java, garbage collection (GC) efficiency has a huge impact on system performance. When running as it should, GC adds very little overhead to the application, quietly doing its job in the background. When it goes wrong, it results in high CPU usage and long pauses, degrading response times and possibly impacting on other running applications.

Additionally, GC logs...
