Auto Skip
Report Issue
A.
transferTo() only works between network channels; cannot be used between file channels
B.
ByteBuffer loop always faster than transferTo(); zero-copy provides no advantage
C.
transferTo() provides zero-copy at OS level; efficient than ByteBuffer loop; difference notable for large files
D.
FileChannel.transferTo() guarantees copying entire file in single call; no loop needed
