Maybe I missed something, but there doesn't appear to be a benchmark between JNI, JNA, and pInvoke. Most my experience with .NET/Java has shown it is fast enough in most cases, but then run into areas that need to be optimized into Native Code. This calling of Native "C" code can be slow with JNI and generally just fast enough for .NET pInvoke. I haven't ever had a reason to test JNA.
