Your JVM may experience performance issues due to an excessive number of Garbage Collection (GC) threads. These can lead to increased context switching, higher CPU consumption, and degraded application response time. The default thread count is based on the number of CPUs, but you can manually adjust it using specific JVM arguments to optimize performance without introducing new problems.
Java's Garbage Collection manages memory by clearing unused space. If the number of GC threads isn't set correctly, it can slow down your application. Balancing the thread count is key to preventing delays and memory issues, ensuring smooth performance.
