I took a profile snapshot while performing Help / Check for Updates and updating my developer IDE.

There is a hot spot in writing to XMLWriter while saving in 
- SimpleArtifactRepositoryIO#write
- ProfileWriter#writeProfile

The XMLWriter uses a PrintWriter without buffering. It likely improves speed when wrapping it into a BufferedWriter.
