This article provides a detailed introduction to achieving dual-machine hot standby with Keepalived, building internal network service load balancing with HAProxy, and resolving NIC soft interrupt issues for network performance optimization. Through real-world cases and detailed configuration explanations, this article helps readers understand the core principles and practical applications of these technologies.</p>/en/archives/02-jvm-debug/Tue, 16 Jan 2018 00:00:00 +0000/en/archives/02-jvm-debug/<h2 id="introduction">Introduction</h2> <p>JVM performance tuning and memory issue troubleshooting have always been significant challenges for Java developers. This article starts from the three core goals of GC tuning and combines them with a real-world off-heap memory leak investigation case to provide a systematic approach to performance tuning and practical troubleshooting methods.</p> <p>In complex distributed systems, memory issues are often the hardest to diagnose. Off-heap memory leaks in particular, occurring outside the JVM heap, are difficult to detect with conventional GC monitoring tools and can easily cause systems to crash suddenly in production environments. This article shares a complete off-heap memory leak investigation process, hoping to provide valuable reference for readers.</p>
