Performance of Banana PI for routing

Saw some threads about the Banana Pi as a router, but I didn't see specific benchmark numbers. I'm looking only at wired 1 gigabit performance for a LAN to WAN router (I have separate APs for WiFi and thus don't need the router to do wireless).

Can anyone supply benchmark results for the following:

  1. LAN to WAN via NAT IPv4 Performance
    • Can it saturate a gigabit?
  2. LAN to WAN via NAT IPv4 from 3+ LAN clients
    • Can it saturate a gigabit to the WAN still or do all 3 clients get < 1/3rd?
  3. Maximum number of active network connections supported
    • Can hit handle 4+ LAN clients sending 262,144+ active connections combined?
    • Ex: Multiple LAN sources performing nmap scans out to a target on the WAN
      sudo nmap -sU -p- -T5 --defeat-icmp-ratelimit --min-rate 1000 --stats-every 5s scanme.nmap.org

Which one of the many and varied BPi products are you talking about?
