I've noticed that nmap on FreeBSD is particularly lame at scanning the local network. If the majority of the addresses on the local network are unoccupied, then it will pause with a 'no buffer space available' message and pause for 15 or 20 seconds each. This seems to be due to it wanting to send a number of packets to the same addresses and when the arp is not resolved we're putting a negative entry in the routing table. .... or at least that was the behaviour. Recent -CURRENTS don't even seem to try to send arp entries as the arp table isn't full of incomplete entries as it was before.
