Wow, thats it! The delay is gone.

For now I am satisfied that the delay is gone and will read up some more on
tcp_nopush.

For the future: Is there any information on why the combination of
tcp_nopush and proxy_cache_background_update create the delay and not the
STALE response you get when the backend ist down and
proxy_cache_background_update is off?
