The allocation is done through native methods, and it's likely to be significantly more expensive than creating non-direct buffers. I am not saying that we shouldn't use ByteBuffers for the low-level access API, I am saying that we should be very careful how we handle them, and what kind of buffers we pass around, so the drawbacks don't outweigh the speed advantages obtained by having I/O devices writing directly in the memory areas managed by direct buffers.
