Hi Wabe

IP changes dynamically, is assigned by Networkmanager with dhclient use 
flag.
I changed /etc/hosts as Mick/Michael pointed out in an other reply, and 
this solved the slow response. Here the relevant part of the corrected, 
working /etc/hosts:

# IPv4 and IPv6 localhost aliases
127.0.0.1       cadd.homeLAN localhost
::1             cadd.homeLAN localhost cadd

Thanks for your time looking into it and the hints.
