Probably here is a problem: many Strings created and discarded may
stimulate GC.

Can you rewrite this to

    # buf should be allocated before the loop.
    input.sysread(count, buf)
    output.syswrite(buf)

and test its performance?  Here buf is updated by sysread and no more
extra Strings are created.
