Hmm - does not show anything special either. But during tries to track this down it showed that most of the time I received TCP_MEM_HIT, but sometimes a row of TCP_REFRESH_MISS occured for a duration of 10 or 20 seconds (1 request per sec) out of no obvious reason and only sporadic. It seems this occured with and without the collapsed forwarding-patch. I'll try to find a good way to reliable diagnose it before continuing this thread. Thank you for your help so far.
