CPU spikes are one of the most common performance challenges faced by Java applications. While traditional APM (Application Performance Management) tools provide high-level insights into overall CPU usage, they often fall short of identifying the root cause of the spike. APM tools usually can’t pinpoint the exact code paths causing the issue.

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.
