Edit Question
Title
Body
I'm developing a JNI implementation similar to sun.misc.Unsafe but with extended memory management. Why are the call times of native methods from sun.misc.Unsafe and from my developed library extremely different? Some numbers: sun.misc.Unsafe.getInt(address) takes ~1ns when my similar method takes ~10ns Both implementations are quite the same, following the source code of OpenJDK, just returning the variable by pointer. Both are registered in the same manner. How can I speed up JNI calls? What makes Unsafe performance so special? Thanks, Yury/
