Thank you. I found those options after posting the mail, and have now
set to 600 and 300 respectively.
I'm impressed how effective the packet cache is:
root at wrn-dns1:~# rec_control get packetcache-hits
root at wrn-dns1:~# rec_control get packetcache-misses
root at wrn-dns1:~# rec_control get cache-hits
root at wrn-dns1:~# rec_control get cache-misses
