OK ... I finally give up, it's a waste of time. I thought that was just the plain config writing to /dev/null w/o any bells and whistles. This, together with the messy thread makes me strongly belive we'll go nowhere that permits us to draw any conclusions. Should you come up with a stable situation that tell where a bottleneck may be, I am happy to join this thread again, but until then I can't spent the time. I also doubt we'll ever arrive there..
