It does. And allocating your space exactly 50:50 makes a noticeable
difference.

the plain Buffered reader was done like this:

final BufferedReader ibr = new BufferedReader( new FileReader(
sampleDataFile ), buffsize / 2 );

It got whatever the default buffering on the internal inputstream is.
It is not as fast as specifying buffers for the internal inputstream,
lego-style.
