It has much more polling related sysctl tunable. We've got too FreeBSD 5 firewalls at our site (which are doing just fine), and I'm gonna upgrade them to 6.0 one of these days. Look at "netstat -s" to see how many packets are "broken". Maybe your switch/cabling can't cope with the load. Where are the figures from the top output. I only see percent signs. Try running iperf. It's really easy. Just install the port on two boxes, run iperf -s on one and iperf -c <other IP> on the other.
