Garbage Collection is a facet often disregarded and underestimated, yet beneath its surface lies the potential for profound impacts on your organization that reach far beyond the realm of application performance. In this post, we embark on a journey to unravel the pivotal role of Garbage Collection analysis and explore seven critical points that underscore... Continue Reading →
The Parallel garbage collector in JVM enhances processing by utilizing multiple threads, reducing GC pauses. It suits applications focusing on throughput, batch processing, or larger heap sizes. Configuration involves specific JVM arguments to fine-tune heap and generation sizes, manage GC pause times, and optimize performance, requiring continuous monitoring for best results.
ZGC is a specialized Java garbage collector that efficiently manages large heaps with minimal pause times, ideal for memory-intensive applications. This post details tuning parameters like heap size, concurrent GC threads, and NUMA support, emphasizing the importance of analyzing GC logs for performance optimization to enhance application efficiency.
Automatic garbage collection in programming languages like Golang, Java, and Python simplifies memory management but may lead to high CPU usage. This article discusses methods to measure CPU consumption caused by garbage collection, including GC log analysis, monitoring tools, and examining CPU usage by GC threads, enabling performance optimizations for applications.

Modern programming languages offer automatic garbage collection, which simplifies memory management but can lead to increased CPU consumption and higher cloud hosting costs. This article outlines five strategies for developers to mitigate these issues: analyzing GC logs, switching GC algorithms, minimizing object creation, adjusting heap size, and scaling instances. Each approach aims to optimize application performance and reduce resource expenses.
Developers once managed memory manually, leading to leaks. Java's 1995 introduction of automatic garbage collection shifted this responsibility to the JVM. GC throughput, measuring time spent on processing versus garbage collection, is crucial for performance. Optimizing this throughput requires addressing issues like memory leaks, tuning, and resource allocation for better application efficiency.

This post discusses the advantages of setting the initial heap size equal to the maximum heap size for Java applications. Benefits include improved availability, performance, and application startup time while maintaining cost-effectiveness in cloud environments. It highlights real-world tests showing better response times and reduced garbage collection pause times with this configuration.
