Is Java's System.arraycopy() efficient for small arrays?

Question

Is Java\'s System.arraycopy() efficient for small arrays, or does the fact that it\'s a native method make it likely to be substantially less efficient than a s

Answer 1

Native functions should be faster than JVM functions, since there is no VM overhead. However for a lot of(>1000) very small(len<10) arrays it might be slower.
