Actually, on RELENG_5, I think the default is now zero.
With a releng_5 BETA7 box in between 2 other hosts, with idle_poll set to
the default on zero, using
/usr/local/netperf/netperf -l 30 -H 10.10.10.1 -i 10,2 -I 99,10 -t
UDP_STREAM -- -m 1000 -s 32768 32768
I see about 483Mb. If I set it to 1,
I get just over 500Mb. This was with an HZ of 1000
