title: java file move high performance
body: <p>I am writing a media transcoding server in which I would need to move files in the filesystem and till now I am in the dilemma of whether using java renameTo can be replaced by something else that would give me better performance. I was considering using exec("mv file1 file2") but that would be my last bet.
  Anyone has had similar experiences or can help me find a solution?</p>
