Comment (by iwakeh):

 Replying to [comment:5 karsten]:
 > I tried out switching to Jackson, and it turns out that we can save 30%
 of overall time (for writing details documents). That's almost 4 minutes
 every hour. Sounds like a good idea to me.

 Yes, this is a good idea!  I added a child ticket for this task, which can
 easily be treated independently to possibly additional changes.  All Gson-
 Jackson discussion can be moved there.  A first step for sure.

 I look further and post findings here.
