 I have increase my app publish message rate(8 times), 
 from client is 3.5M/s, state is flow
 publish rate is 20000/s, state is running
 I am strange is why the before publish rate is only 2000/s(300K/s), the connection is still in flow state.

You can simulate this setup with PerfTest [1]:

./runjava.sh com.rabbitmq.examples.PerfTest -y 0 -t "fanout"

and tweak various options such as message size.

For example, running PerfTest with the options above stabilizes
at about 65-70 K messages per second on my (1 gen old, not maxed-out)
MacBook Pro.
