Answer 1

Try reading by BufferedInputStream, wrapped around the InputStream. That should speed it up significantly.

Instead of:

-------------------------
InputStream is = new FileInputStream('filename');
...
is.read()
...
is.close();
-------------------------

Use:

-------------------------
InputStream is = new FileInputStream('filename');
BufferedInputStream bis = new BufferedInputStream(is);
...
bis.read();
...
bis.close();
is.close();
-------------------------

Similarly, instead of just OutputStream to write, you should also wrap with a BufferedOutputStream.
