- Have you tried increasing the number of the ring buffer cells like
  PCAP_FRAMES=max?

- I suppose your ruleset is already optimized

- Deactivate preprocessor frag2 if you're behind a defragmenting
  firewall (Netfilter always defragments if you turn on conntrack)

- Blend out the encrypted traffic (SSL/HTTPS/IMAPS/POP3S)
