No source code for the test framework; can't see how the code is called. If there are repeated calls through JNI, JNI transit time can often be a significant factor. How many times through the benchmark? Did the JIT get a chance to warm up? Caliper provides a framework that can be used to properly assess performance. There's no benchmark here without seeing a more complete picture.
