Optimize Java memory allocation and Garbage Collector flags to eliminate stutter spikes on Java game servers. ## Steps 1. Understand how Garbage Collection (GC) pauses occur when Java clears unused memory objects. 2. NodeFlux container startup parameters automatically include optimized G1GC flags based on Aikar recommendations. 3. Ensure your server allocation is not over-committed; allocating too close to container RAM limits causes OS-level swapping. 4. Avoid setting artificial MaxGCPauseMillis values below 50ms, which causes GC threads to work inefficiently. 5. Review GC log statistics in startup outputs to ensure garbage collection pauses remain under 20ms average. ## Notes - G1GC (Garbage-First Garbage Collector) is the standard collector for modern 64-bit Java runtimes. - Using -XX:+UseG1GC with proper region sizes prevents full world-stop GC pauses.
