Java 21's ZGC trades a little CPU for zero stop-the-world pauses. No more IPC timeouts and retries. Netflix runs servers hotter with fewer instances. #Java #ZGC #Performance

JEP 546, Adaptive Heap Sizing for ZGC, is now a Candidate! ZGC will adapt heap size to application demand and available host CPU/memory—reducing manual tuning while balancing throughput, latency, GC CPU, and neighboring workloads. openjdk.org/jeps/546

JEP 545, Faster Startup and Warmup with ZGC, is now a Candidate! Complementing Leyden AOT for startup and warmup, ZGC reduces the trade-off between fast startup with a small initial heap and smoother performance with a large, pre-touched heap 😀
