This document discusses how the Azul Platform Prime JVM can improve Kafka performance without any code changes. It summarizes that the Azul JVM replaces HotSpot with the C4 garbage collector and Falcon JIT compiler to eliminate stop-the-world garbage collection pauses and improve adaptive compilation. This results in up to 20% better performance for Kafka workloads and allowed one customer to reduce their cloud hardware costs by 15% while maintaining throughput.
