robert watson's posts to freebsd-net indicate that in high bandwidth, low 
latency links (such as your average LAN), inflight enabled actually drops 
performance.

on a Celeron 400Mhz with 128MB RAM and intel etherexpress onboard NICs, 
i've been able to get near wire speed throughput (80+Mbps with iperf) on 
the 1.2 and 1.3a1 images, with or without inflight enabled. this doesnt 
indicate much however for the Celeron is beefy enough a processor for what 
we're throwing at it. we'd need to use a processor which maxed out /before/ 
wire speed throughput was reached, if we're to really benchmark the IP 
stack difference between freebsd 4.x and 6.0.

a better benchmark would be doing the same on the soekris net45xx and 48xx 
boxes for the lower speed processor there would max out before the wire 
speed is ever reached.
