Hi Marcel,

Are you committing data with hard commits or soft commits?  I've seen systems 
where we've inadvertently only used soft commits, which means that the entire 
transaction log has to be re-read on startup, which can take a long time.  Hard 
commits flush indexed data to disk, and make it a lot quicker to restart.
