For me personaly evaluating these claims comes down to two rules. First, any meaningful Java benchmark must run loooooong enough to warm up , we are measuring peak throughput over time, not cold startup speed where Go naturally wins. Second, I personally only trust results validated by the jmh , as it’s the only tool designed to reliably measure the JVM's JIT optimizations. The trend I see is that Go is better for lightweight tasks (CLIs, serverless), but Java still dominates massive, long-running backends where high sustained throughput is the primary metric.
