Description
JDK-8066867 provides a basic implementation that transfers bytes from the input stream to a given output stream. Input streams can override this method to provide a more efficient transferTo implementation, the most obvious being ByteArrayInputStream. There are possibly others.
Comments
JDK-8180451 implemented transferTo() for ByteArrayInputStream. The only other InputStream subclass in java.io for which a more performant override appears possible is StringBufferInputStream but it is deprecated so this is probably not worth doing. Resolving as a duplicate.
