Here is an interesting little test to run on current kernels. Run it as

# Enter first three parts of your IP num. below (e.g. for 192.168.3.5)

NET=192.168.3
HOSTNUM=254
while [ $HOSTNUM != 0 ]
do
ping -s $[$RANDOM % 1490] -c1 $NET.$HOSTNUM > /dev/null 2>&1 &
HOSTNUM=$[$HOSTNUM - 1]
true; true # waste a few more ticks
kill $! > /dev/null 2>&1
