I wonder how long 'netstat -rn' takes on *BSD with 54k routes.

6 seconds (output to /dev/null) on a Pentium something-or-other
running BSD/OS 3.1.

How about 'netstat -rn | wc -l'

Good test for a GRF router which runs BSD. We see almost exactly this many
routers and when we reconfig a router we use the command a lot to what
routes coming in. In most cases with a full 51-56k routes it is about
3-4secs.

GRF is a 166mhz pentium, 2.1BSDI, 512meg RAM.
