excellent, doing that now.

the question was less about the data they carry - I know they should be 
in sync. I was more looking for things like "don't ever use X by 
default because they can't handle the load without you already" or the 
like :)

so that is what I need to recommend in the manpage?

I have looked a bit more and spend some time with
  http://www.ripe.net/ripe/docs/db-query-manual.html

>From that document it sounds like the penalty is only there if I query 
person/role data. That does not match what I see tho - I do not query 
anything but aut-num, as-set and route objects. Still, I am suspect to 
the delay.
