Based on the screen you shared, I assume that you didn't perform any warm-up iterations, which are crucial to allow JIT to kick in. Have you followed any guidelines regarding (micro)benchmarking (e.g., described here: https://www.oracle.com/technical-resources/articles/java/architect-benchmarking.html)?

Also, it would be good to see on what data you ran the benchmark. Would you mind sharing it?
