I just had a slow "switch branch" which gave me enough time to sample it.
 org.eclipse.jgit.util.io.AutoCRLFOutputStream.write ()
directly calls 
 java.io.FileOutputStream.write ()

.. for every line?!

would you mind to wrap that FileOutputStream into a BufferedOutputStream to reduce system calls?
