You're using the InputStream inefficiently, since it's not buffered.
That's what kills performance.  Anything done after that doesn't matter.

Okay, in this case Builder gets an InputStream and passes it to the
parser, which buffers it internally, possibly using a BufferedInputStream
or possibly with its own mechanism.  Big win.

If a soldier is asked why he kills people who have done him no harm, or a
terrorist why he kills innocent people with his bombs, they can always
reply that war has been declared, and there are no innocent people in an
enemy country in wartime.  The answer is psychotic, but it is the answer
that humanity has given to every act of aggression in history.  --Northrop
