The JVM’s just-in-time (JIT) compilation delivers peak performance—but only after warming up. For low-latency systems (serverless, real-time trading, microservices), slow warmup means: Higher tail latencies in cloud deployments Wasted CPU cycles during cold starts Poor user experience in bursty workloads This guide covers proven techniques to slash JVM warmup time, with benchmarks and real-world tuning strategies. 1. Why Warmup …
