Comment:

 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.

 I uploaded my branch with temporary commits
 [https://gitweb.torproject.org/user/karsten/onionoo.git/log/?h=task-25815
 here]. I did ''not'' verify that all outputs are correct with regard to
 unicode character escapes and character encodings in general. I only
 looked at performance.

 For the moment, I'm giving this ticket back to metrics-team. I might grab
 it back next week, unless somebody else takes it first.
